[0056] The technical solutions in the embodiments of the present invention will be described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0057] In existing advertising practices, advertisers usually design some patterns and texts by themselves. For example, corporate logos, slogans, etc. are used as sticker elements and superimposed on advertising pictures to enhance the advertising effect.

[0058] However, when the area of ​​a single sticker element to be added is too large, or the number of sticker elements to be added is large, the added sticker elements are likely to cover the main content of the advertisement image, thereby affecting the effect of the advertisement.

[0059] In view of the above problems, an embodiment of the present invention provides a sticker adding method, such as Figure 1As shown, including:

[0060] S101, obtaining an initial advertisement picture; the initial advertisement picture is a picture to which stickers are to be added;

[0061] S102, determining non-transparent pixels of the sticker, a planned location for adding the sticker in the initial advertisement picture, and an area where the non-transparent pixels in the initial advertisement picture are located, wherein the non-transparent pixels in the initial advertisement picture represent the main content of the initial advertisement picture;

[0062] S103, based on the non-transparent pixels of the sticker, the planned adding position of the sticker in the initial advertising picture, and the area where the non-transparent pixels in the initial advertising picture are located, determining the quantitative relationship between the non-transparent pixels of the sticker and the initial advertising picture, and calculating the occlusion index of the sticker on the initial advertising picture;

[0063] S104, when the occlusion index is less than a preset threshold, superimpose stickers at planned locations in the initial advertisement image to obtain a target advertisement image.

[0064] The sticker adding method provided by the embodiment of the present invention can be applied to a picture editing device, for example, the picture editing device can be a server, a terminal, etc.

[0065] For example, the sticker adding method provided in the embodiment of the present invention can be applied to the process of an advertiser generating an advertisement. In this case, the picture editing device can be an electronic device that provides picture editing functions to the advertiser, such as a browser.

[0066] The sticker adding method provided by an embodiment of the present invention calculates an occlusion index reflecting the degree of occlusion of the initial advertising image at the planned adding position, and when the occlusion index is less than a preset threshold, superimposes stickers at the planned adding position in the initial advertising image to obtain a target advertising image. In this way, sticker elements at the planned adding position corresponding to the occlusion index being less than the preset threshold can reduce the occlusion of the main content of the advertisement by the sticker elements.

[0067] The main content in the initial advertisement picture can also be understood as the effective information in the initial advertisement picture. Specifically, the main content can include people, objects, etc. in the initial advertisement picture.

[0068] In one approach, a main content recognition model may be obtained by training a plurality of sample images in advance, and the initial advertisement image may be input into the main content recognition model, and the main content of the initial advertisement image may be determined by the main content recognition model.

[0069] Specifically, the main content recognition model can be obtained by training multiple sample images in the following ways:

[0070] Obtaining multiple sample images and marking information of the main content of each sample image, such as marking people and objects in the initial advertisement image with a rectangular frame, wherein the image can be marked using a marking method in the related art, which is not limited in the embodiment of the present invention;

[0071] A sample image is selected, and the sample image is input into the initial model. The initial model outputs the recognition information of the main content in the sample image, and the recognition information is compared with the marking information. If the difference between the recognition information and the marking information exceeds the preset difference, the parameters of the initial model are adjusted until the difference between the recognition information and the marking information is less than the preset difference. Then, the method returns to execute the selection of a sample image and subsequent steps until the number of training times reaches the preset number, and the training is terminated to obtain a trained main content recognition model, wherein the preset difference, the preset number of times, etc. are determined according to actual needs or experience.

[0072] The identification information may be a picture marked with the main content of the sample, or may be the position information of the identified main content in the initial advertisement picture.

[0073] The initial model can be any type of artificial intelligence model, such as a deep learning model. The specific model training process is carried out with reference to the training method of the artificial intelligence model in the relevant technology, which will not be repeated here.

[0074] In the embodiment of the present invention, the main content of the initial advertisement picture is represented by non-transparent pixels in the initial advertisement picture.

[0075] Reference Figure 1 , the embodiment of the present invention describes the sticker adding method in detail.

[0076] S101, obtaining an initial advertisement picture; the initial advertisement picture is a picture to which stickers are to be added.

[0077] The initial advertising images may include images in various forms, such as photographs, screenshots, hand-drawn images, and images generated using AI (Artificial Intelligence) technology.

[0078] The initial advertisement picture may be a picture provided by the advertiser for promoting the business. In the embodiment of the present invention, after adding sticker elements to the initial advertisement picture, the sticker elements will not block the main content of the advertisement as much as possible, so that the advertisement recipient can obtain more information through the advertisement with the sticker elements added, thereby improving the advertising effect.

[0079] Stickers, which can also be understood as sticker elements, refer to elements added to the initial advertising image that can enhance the expressive effect of the image.

[0080] Sticker elements can include elements that can add additional information to the image, such as a sticker element with the text "70% off all items" or a sticker element with the logo of company A.

[0081] The sticker elements may include elements that can increase the beauty of the picture, for example, a sticker element with a pattern of "butterfly" is added to the "forest" picture; and sticker elements with patterns of "cake", "star", etc. are added to the "birthday photo" picture.

[0082] In S102, in a scenario where the advertiser generates an advertisement in real time, the current location selected can be used as the planned adding location in real time during the process of dragging the sticker on the advertisement picture by using a mouse, gestures, etc. to select a planned adding location.

[0083] Alternatively, a position that has been determined may be used as a planned adding position. In this case, the planned adding position may also be referred to as a target planned adding position.

[0084] In the case where the advertiser selects the planned adding position in real time, in the embodiment of the present invention, determining the non-transparent pixels of the sticker, the planned adding position of the sticker in the initial advertisement picture, and the area where the non-transparent pixels in the initial advertisement picture are located may include:

[0085] Determine the non-transparent pixel points of the sticker and the non-transparent pixel points of the current image area, wherein the current image area represents the area overlapping with the initial advertising image when the sticker is at the current position in the initial advertising image, and the current position is used as the planned adding position.

[0086] In one possible implementation, before S102, the process may further include obtaining a plurality of original sticker elements; and splicing the plurality of original sticker elements to obtain stickers.

[0087] It can be understood that the sticker added to the initial advertisement image in the embodiment of the present invention may be a single sticker or a sticker obtained by splicing multiple stickers.

[0088] In S103, the method for triggering the calculation of the occlusion index of the sticker on the initial advertisement image is as follows:

[0089] In one possible implementation, after determining the target planned adding position, the occlusion index of the sticker on the initial advertisement image is calculated.

[0090] In another possible implementation, in response to detecting a selection operation on an initial advertising image, an occlusion index of the initial advertising image by the sticker is calculated, wherein a current position corresponding to the selection operation is used as a planned adding position.

[0091] Regarding the situation in which the occlusion index of the sticker on the initial advertising image is calculated in response to detecting a selection operation for the initial advertising image, it can also be understood that, during the process in which the operator selects a planned adding position for the advertising image in real time, the occlusion index of the sticker on the initial advertising image is calculated in real time corresponding to the currently determined planned adding position.

[0092] The selection operation may also include dragging stickers using a mouse, gestures, etc.

[0093] Specifically, in response to detecting a selection operation on the initial advertisement image, the current position of the sticker in the initial advertisement image is determined, and the current position is used as the planned adding position, and then steps S102 and S103 are executed.

[0094] For example, in a scenario where an advertiser generates an advertisement in real time, while the advertiser drags a sticker to the position of an advertisement picture using a mouse, gestures, etc., the currently selected position, that is, the current position, is determined based on the operation of dragging the sticker to the position of the advertisement picture using a mouse, gestures, etc. After determining the current position, the current position is used as a planned adding position, and steps S102 and S103 are executed.

[0095] Specifically, based on the non-transparent pixels of the sticker, the planned adding position of the sticker in the initial advertising picture, and the area where the non-transparent pixels in the initial advertising picture are located, the quantitative relationship between the non-transparent pixels of the sticker and the initial advertising picture is determined, and the occlusion index of the sticker on the initial advertising picture is calculated, including:

[0096] Based on the quantitative relationship between the non-transparent pixels of the sticker and the non-transparent pixels of the current image area, the occlusion index of the initial advertisement image by the sticker at the current position is calculated;

[0097] In this case, when the occlusion index is less than a preset threshold, stickers are superimposed at the planned position in the initial advertising image to obtain the target advertising image, that is, stickers are superimposed at the current position in the initial advertising image to obtain the target advertising image.

[0098] In which, in response to detecting a selection operation on the initial advertising picture, determining the current position of the sticker in the initial advertising picture may include: in response to a placement operation of the sticker in the initial advertising picture, determining the current position of the sticker in the initial advertising picture.

[0099] In the embodiment of the present invention, the number of stickers targeted by the placement operation may be one or more.

[0100] When the number of stickers targeted by the placement operation is one, the current position of the sticker in the target image indicates the position of the sticker in the target image.

[0101] When the number of stickers targeted by the placement operation is multiple, the current position of the sticker in the target image represents the position of each of the stickers in the target image.

[0102] The placement operation of stickers in the target image may include a selection operation for stickers and a move operation for the selected stickers. For example, to place stickers in the initial advertisement image, for the placement process of a single sticker, the operator first selects which sticker to place in the initial advertisement image, and then moves the sticker to the initial advertisement image.

[0103] In one practicable manner, the selected sticker may include elements customized by the provider of the initial advertising image according to demand.

[0104] The provider of the initial advertising image can customize stickers that meet actual needs in advance and upload them to the platform that provides sticker adding services. In this way, the stickers are more consistent with the initial advertising image, making the generated final advertising image more meet actual needs. In the scenario of generating advertising images, the communication effect of the advertising images is improved.

[0105] In another achievable manner, the selected stickers may include elements pre-randomly generated by a platform providing sticker adding services.

[0106] The platform that provides sticker adding service can pre-generate a large number of stickers randomly, and can store these stickers in a material library, so that the operator can select the stickers that he wants to add to the initial advertising picture in the material library.

[0107] The moving operation for the selected sticker may include a dragging operation and a scaling operation for the sticker, wherein the dragging operation refers to the operation of moving the sticker position; and the scaling operation refers to the operation of changing the sticker size.

[0108] The operator places the selected sticker in the initial advertisement picture at a position where the sticker is expected to overlap with the initial advertisement picture by dragging and zooming, which is also the current position of the sticker in the initial advertisement picture determined by the picture editing device in response to the placement operation.

[0109] Understandably, since the position is only selected by the operator based on subjective judgment, the position where the sticker is superimposed will not excessively block the content of the initial advertisement picture. Therefore, it cannot be determined that this position is definitely a position that will not excessively block the content of the target picture, and the picture editing device is required to further determine the rationality of the current position, that is, through S102 and S103, calculate the blocking index of the sticker on the initial advertisement picture if the sticker is superimposed at the current position.

[0110] In S103, the following method may be used to calculate the occlusion index of the sticker on the initial advertisement image:

[0111] In one implementable method, the non-transparent pixels of the sticker and the non-transparent pixels of the overlapping area in the initial advertising image can be determined, wherein the overlapping area is the area that overlaps with the initial advertising image when the sticker is at the planned addition position in the initial advertising image, and based on the quantitative relationship between the non-transparent pixels of the sticker and the non-transparent pixels of the overlapping area in the initial advertising image, the occlusion index of the sticker on the initial advertising image when it is at the planned addition position is calculated.

[0112] Among them, the ratio of the number of non-transparent pixels of the sticker and the number of non-transparent pixels in the overlapping area of ​​the initial advertising image can be used as an occlusion indicator of the initial advertising image when the sticker is planned to be added.

[0113] In another possible implementation method, the non-transparent pixels in the overlapping area of ​​the stickers and the non-transparent pixels in the initial advertising image can be determined, and based on the quantitative relationship between the non-transparent pixels in the overlapping area of ​​the stickers and the non-transparent pixels in the initial advertising image, the occlusion index of the initial advertising image by the stickers at the planned addition position can be calculated.

[0114] Among them, the ratio of the number of non-transparent pixels in the overlapping area of ​​the sticker to the number of non-transparent pixels in the initial advertising image can be used as an occlusion indicator of the initial advertising image when the sticker is planned to be added.

[0115] In another possible implementation method, the planned location of the sticker in the initial advertising image, the non-transparent pixels of the sticker, and the non-transparent pixels of the initial advertising image can be determined, and based on the quantitative relationship between the planned location of the sticker in the initial advertising image, the non-transparent pixels of the sticker, and the non-transparent pixels of the overlapping area in the initial advertising image, the occlusion index of the sticker on the initial advertising image can be calculated.

[0116] Among them, the ratio of the number of non-transparent pixels of the sticker to the number of non-transparent pixels of the initial advertising picture when the sticker is at the planned adding position in the initial advertising picture can be used as an occlusion indicator of the initial advertising picture when the sticker is at the planned adding position.

[0117] Determining a non-transparent pixel can also be understood as determining the transparency information of the pixel. The transparency information is used to indicate whether the pixel contains valid information. It is generally believed that the higher the transparency, the less valid information the pixel contains; the lower the transparency, the more valid information the pixel contains. In an embodiment of the present invention, the pixels can be divided into non-transparent pixels whose transparency information is non-transparent and transparent pixels whose pixel information is transparent.

[0118] In one feasible method, the color value can be used to evaluate the amount of effective information contained in a pixel. Pixels with color values ​​greater than a preset color value threshold (dark color value) contain more effective information, and the pixel information of the pixel can be set to non-transparent; pixels with color values ​​less than a preset color value threshold (light color value) contain less effective information, and the pixel information of the pixel can be set to transparent. Furthermore, the embodiment of the present invention can obtain the non-transparent pixels of the sticker by detecting the color value of each pixel of the sticker.

[0119] The transparency information of the sticker can be stored in a two-dimensional array. In one achievable manner, the transparency information of the sticker can be saved in a two-dimensional array through a preset API of the browser. Among them, four consecutive elements in the two-dimensional array can be used to represent the four attribute values ​​of a pixel, and the attribute value represented by the fourth element can be the transparency information of the pixel.

[0120] For example, four consecutive elements in a two-dimensional array can represent the red (R), green (G), blue (B), and transparency (Alpha, A for short) values ​​of a pixel respectively. If the A value of a pixel is greater than 0, it means that the pixel is visible, that is, non-transparent. When the image editing device detects that the A value of a pixel is greater than 0, it determines that it is a non-transparent pixel. The above-mentioned method of representing the attribute value of a pixel with R, G, B, and A values ​​can also be called RGBA color representation (additional transparency color representation).

[0121] In one feasible method, the image editing device can traverse all stickers and parse each pixel in the stickers to obtain the colored pixels, or non-transparent pixels, and update the pixel information of the non-transparent pixels to the same coordinates in the two-dimensional array, thereby marking the non-transparent pixels in the two-dimensional array.

[0122] For some stickers, their combination can bring different expressive effects. For example, a sticker with an "arc" pattern and a sticker with a "star" pattern can express the combined effect of a "shooting star" when the two are combined.

[0123] Therefore, the operator can place different sticker combinations in the initial advertising image to achieve different expression effects. In this process, different stickers may overlap. Figure 2 As shown, in the shadow part, sticker A and sticker B overlap. At this time, if we still determine the occlusion of each sticker on the initial advertising picture separately, it is obviously inaccurate.

[0124] Furthermore, in the embodiment of the present invention, the sticker area when the sticker is at the current position refers to the joint coverage area of ​​the stickers. Figure 3a As shown, sticker area 301 is the area covered by sticker A. When the number of stickers targeted by the placement operation in S102 is multiple, such as Figure 3b , sticker area 302 refers to the entire area covered by these stickers.

[0125] In a possible embodiment, determining the sticker area when the sticker is at the current position may include: for each sticker, drawing the contour area of ​​the sticker; the contour area includes each pixel whose transparency information of the sticker is non-transparent; and taking the union of the contour areas of each sticker at the current position to obtain the sticker area.

[0126] Each sticker refers to each sticker in the stickers targeted by this placement operation. According to the transparency information of each pixel in each sticker, a contour area corresponding to each sticker is drawn, including all non-transparent pixel information in the sticker. By taking the union of each contour area drawn at the current position, the sticker area corresponding to the sticker targeted by this placement operation is obtained.

[0127] In another possible embodiment, for each sticker, the transparency information is the position information of each non-transparent pixel; and the sticker area is drawn using the position information.

[0128] The position information of each pixel whose transparency information is non-transparent in each sticker placed in this operation is counted. When the position information of each pixel whose transparency information is non-transparent overlaps, only this is counted. In this way, the coverage area of ​​the non-transparent pixel points in each sticker at the current position can be drawn, that is, the sticker area.

[0129] According to the embodiments of the present invention, a plurality of stickers can be spliced ​​together to obtain a continuous sticker area, and the occlusion of the initial advertising image when multiple stickers are added can be determined more effectively in the future, thereby making the detection of whether the content of the initial advertising image is occluded more accurate.

[0130] The sticker adding method provided by the embodiment of the present invention may further include: constructing a virtual container.

[0131] Constructing a virtual container, the size of the virtual container being the same as the size of the video playing window playing the initial advertisement image;

[0132] S101 includes: adding an initial advertisement image to a virtual container;

[0133] Determining the non-transparent pixel points of the sticker in S102 includes: writing the sticker into a virtual container; creating a two-dimensional array in the virtual container, where each element position of the two-dimensional array corresponds to a pixel point of the initial advertising image; traversing each pixel point of the sticker, when a pixel point is a non-transparent pixel point, updating the non-transparent pixel point to the two-dimensional array according to the current position of the sticker in the initial advertising image, and the current position is the planned adding position;

[0134] S103 includes: counting the number of non-transparent pixels of the sticker based on the updated two-dimensional array; determining the ratio of the number of non-transparent pixels of the sticker to the number of non-transparent pixels in the initial advertising picture area when the sticker is planned to be added in the initial advertising picture, as an occlusion indicator of the sticker on the initial advertising picture.

[0135] The virtual container can be understood as a virtual interface that can simulate the sticker process. In a possible implementation, the virtual container can be constructed using the browser's Canvas. The size of the virtual container can be the same as the size of the initial advertisement image.

[0136] Then, the initial advertisement image may be added to the virtual container.

[0137] Since the size of the virtual container is the same as the size of the initial advertisement image, after the initial advertisement image is added to the virtual container, the initial advertisement image can be well adapted to the virtual container. The process of adding the initial advertisement image to the virtual container can also be considered as instantiating the virtual container. This process can be performed in memory.

[0138] In response to a placement operation of the sticker in the initial advertisement picture within the virtual container, a current position of the sticker in the initial advertisement picture is determined using the virtual container.

[0139] The image editing device (a browser in the embodiment of the present invention) can obtain addable stickers according to a provided API (Application Programming Interface) after the initial advertisement image is added to the virtual container. In a possible implementation, the addable stickers can be a DOM (Document Object Model) instance customized by the provider of the initial advertisement image.

[0140] The image editing device can display these addable stickers to the operator so that the operator can select from the displayed stickers. In response to the operator's placement operation on the sticker in the initial advertisement picture in the virtual container, the current position of the sticker in the initial advertisement picture is determined using the preset function of the virtual container.

[0141] In a possible implementation, when the addable stickers are customized DOM instances by the provider of the initial advertising image, since it can be considered that these stickers do not have elements unrelated to the initial advertising image, all DOM instances can be directly copied to the virtual container.

[0142] Since the size of the virtual container is the same as the size of the initial advertisement image, in the embodiment of the present invention, determining the position of the sticker pixel added in the initial advertisement image is essentially determining the position of the sticker in the virtual container. The position of the sticker in the virtual container can be determined by constructing a specific coordinate system in the virtual container, for example, taking the center point of the virtual container as the origin, constructing a coordinate system with the positive directions of the y-axis and the x-axis upward and to the right respectively, to determine the position of the sticker in the coordinate system.

[0143] Furthermore, the virtual container can be used to determine the non-transparent pixels of the sticker.

[0144] By using the preset function of the virtual container and based on the current position of each sticker in the virtual container, the stickers are spliced ​​to obtain a continuous sticker area. The pixel information of the stickers is detected and the content of the sticker area is determined. The relevant content in the aforementioned S103 can be referred to and will not be repeated here.

[0145] Furthermore, based on the non-transparent pixels of the sticker, the planned addition position of the sticker in the initial advertising image, and the area where the non-transparent pixels in the initial advertising image are located, the quantitative relationship between the non-transparent pixels of the sticker and the initial advertising image is determined, and the occlusion index of the sticker on the initial advertising image is calculated.

[0146] Among them, the occlusion index is used to reflect the degree of joint coverage of the initial advertising image by the stickers placed in the initial advertising image at the current position, or the degree of occlusion. If the degree of occlusion is low, it is considered that adding stickers at the current position in the initial advertising image will not block the main content of the initial advertising image; if the degree of occlusion is high, it is considered that adding stickers at the current position in the initial advertising image will block the main content of the initial advertising image, thereby affecting the display effect of the initial advertising image.

[0147] The overlapping area can also be understood as the area where the sticker area is located inside the initial advertising image. It can be understood that only the part of the sticker added in the initial advertising image area can be displayed in the final image (final image). In one example, the ratio of the first number to the second number is calculated to obtain the occlusion index of the initial advertising image; wherein the first number represents the number of pixels with non-transparent transparency information in the overlapping area of ​​the sticker area; and the second number represents the number of pixels with non-transparent transparency information in the initial advertising image.

[0148] The overlapping area may include all or part of the sticker area. If the sticker is completely inside the initial advertising image, the sticker area is the overlapping area. The first number is the number of pixels in the sticker area whose transparency information is non-transparent. If the sticker is partially inside the initial advertising image and partially outside the initial advertising image, the overlapping area may include the part of the sticker area that is inside the initial advertising image. The first number is the number of pixels in the sticker area whose transparency information is non-transparent in the overlapping area.

[0149] Continuing with the aforementioned example of storing sticker pixel information in a two-dimensional array, the embodiment of the present invention can accumulate the number of non-transparent pixels in the global two-dimensional array as a numerator for calculating the occlusion index, that is, the first number.

[0150] In one achievable manner, regardless of the actual information of each pixel in the initial advertisement image, the pixel information of each pixel is considered to be non-transparent, that is, the second number may be the total number of pixels in the initial advertisement image, thereby avoiding the detection of the pixel information of each pixel in the initial advertisement image and saving computing resources.

[0151] In another achievable manner, the method of determining the non-transparent pixels of the sticker in S103 may be referred to to determine the pixels with transparency information as non-transparent in the initial advertising image, thereby improving the accuracy of the second number.

[0152] After obtaining the first number and the second number, the ratio of the first number to the second number may be calculated to obtain the occlusion index of the initial advertisement image.

[0153] In a feasible manner, the first area of ​​the overlapping area in the sticker area and the second area of ​​the initial advertisement image may be determined, and the occlusion index may be obtained by calculating the first area and the second area.

[0154] In S104, when the occlusion index is less than a preset threshold, stickers are superimposed at the planned locations in the initial advertisement image to obtain a target advertisement image.

[0155] The occlusion index is less than the preset threshold, and it is considered that adding stickers at the planned adding position will not excessively block the initial advertising image. Furthermore, when the initial advertising image is an advertising image, adding stickers at the planned adding position will not only not affect the communication of the advertisement, but also effectively improve the display effect of the advertising image by using stickers, and further improve the effective communication rate of the advertisement.

[0156] Conversely, there may also be a situation where the occlusion index is not less than the preset threshold.

[0157] In one possible implementation for a situation where the occlusion index is not less than a preset threshold, the image editing device may be adaptively adjusted to achieve adaptively moving stickers that do not meet the occlusion index away from the main content of the initial advertising image.

[0158] Specifically, when the occlusion index is not less than the preset threshold, the planned adding position is updated, and the process returns to execute S102 and S103 until the occlusion index corresponding to the updated planned adding position is less than the preset threshold.

[0159] In another possible implementation for the case where the occlusion index is not less than a preset threshold, the operator may be reminded to make adjustments, for example, a user who edits the picture, such as an advertiser, may be reminded to make adjustments.

[0160] Specifically, when the occlusion index is not less than a preset threshold, a prompt message is displayed, and the prompt message is used to prompt the user to adjust the size and / or position of the sticker.

[0161] For example, in a scenario where an advertiser generates an advertisement in real time, the advertiser drags a sticker on an advertisement image through a mouse, gesture, etc. to select a planned adding location, and the selected current location is used as the planned adding location in real time.

[0162] When the occlusion index is not less than a preset threshold, the operator is prompted that the initial advertising image is occluded, and in response to a change operation on the sticker, the execution returns to the step of determining the current position of the sticker in the initial advertising image.

[0163] When the occlusion index is not less than the preset threshold, it means that adding a sticker at the current position will occlude the initial advertising image, affecting the information conveyed by the initial advertising image.

[0164] Therefore, the picture editing device can prompt the operator that the initial advertising picture is blocked, for example, by popping up a prompt box containing "Please adjust the sticker" on the operation interface, so that the operator triggers the change operation for the sticker after seeing the prompt information.

[0165] The direct factor causing the occlusion index to be not less than the preset threshold is that there are too many non-transparent pixels in the overlapping area between the sticker area and the initial advertising image. Therefore, according to the number of non-transparent pixels in the area, the embodiment of the present invention can adjust the position and size of the stickers, or even delete some stickers. That is, in the embodiment of the present invention, the change operation can include moving the position of the sticker, and / or adjusting the size of the sticker, and / or changing the type of the sticker, etc.

[0166] When the change operation is to move the position of the sticker, the picture editing device responds to the change operation of the sticker in the initial advertising picture, redetermines the current position of the sticker in the initial advertising picture, and again determines the occlusion index of the initial advertising picture at the changed current position through S102 and S103 to determine whether the sticker can be added at the changed position.

[0167] Generally, adjusting the size of the sticker means reducing the size of the sticker so that the range of the sticker area is reduced, thereby reducing the number of non-transparent pixels in the overlapping area between the sticker area and the initial advertising image. The image editing device responds to the change operation of the sticker in the initial advertising image and re-determines the current position of the sticker in the initial advertising image. S102 and S103 are used to determine the occlusion index of the initial advertising image at the changed current position again, so as to determine whether the sticker can be added at the changed position.

[0168] Changing the type of sticker may include adding a new sticker, that is, the operator triggers a placement operation to place a new sticker in the initial advertising picture; it may also include deleting a sticker, and the operator may delete the sticker in the initial advertising picture by moving the position of the sticker so that the moved sticker does not overlap with the initial advertising picture. The picture editing device responds to the change operation of the sticker in the initial advertising picture, re-determines the current position of the sticker in the initial advertising picture, and again determines the occlusion index of the initial advertising picture at the changed current position through S102 and S103, so as to determine whether the sticker can be added at the changed position.

[0169] The sticker adding method provided by the embodiment of the present invention can be summarized into four steps: collecting and splicing stickers, parsing the pixel information of stickers, calculating the occlusion index, and adjusting the stickers according to the occlusion index. For example, by accurately counting the number of non-transparent pixels in the overlapping area of ​​the stickers and the initial advertising picture, the effective coverage ratio (occlusion index) of the stickers for the initial advertising picture is calculated, and according to whether the occlusion index is less than a preset threshold, it is determined whether the sticker added at the current position will cover the main content of the initial advertising picture, and then the sticker is added at the current position that will not cover the main content of the initial advertising picture. In this way, the communication effect of the initial advertising picture can be improved by adding stickers in the initial advertising picture, and the sticker is guaranteed not to cover the main content of the picture.

[0170] Furthermore, in the field of advertising, for some companies with advertising capabilities, especially advertising platforms and marketing companies that can provide customized advertising sticker adding services, the sticker adding method provided by the embodiments of the present invention can not only ensure that the main content of the advertising image is not covered by stickers, but also use stickers to improve the effective communication rate and advertising effect of the advertisement, enhance the advertiser's advertising experience, and further improve the service quality and customer satisfaction of the advertising platform.

[0171] In one feasible approach, AI technology and deep learning technology can be introduced to accurately identify the main content area of ​​the initial advertising image that contains effective information, and prompt the operator to avoid adding stickers in the main content area, so that the overlapping range of stickers and the initial advertising image can be controlled.

[0172] like Figure 4 As shown, in a specific embodiment, the sticker adding method provided by the embodiment of the present invention may include:

[0173] S401, initializing a virtual container using a browser interface.

[0174] The size of the virtual container may be the same as the size of the initial ad image.

[0175] S402, loading an initial advertisement image in a virtual container and obtaining stickers.

[0176] S402 may be executed in the memory, and the image editing device may copy the sticker DOM instance from the memory.

[0177] S403, writing the sticker into the virtual container.

[0178] In response to the placement operation for the sticker triggered by the operator, the picture editing device writes the sticker to the position where the operator wants to add the sticker in the advertisement picture.

[0179] S403 may be referred to as instantiation of the sticker and the virtual container.

[0180] S404, analyzing the pixel position information of the sticker, and storing the pixel position information in a global two-dimensional array.

[0181] This process is also the process of determining the non-transparent pixels of the sticker.

[0182] The pixel point information of the sticker may include pixel information of each pixel of the sticker. The embodiment of the present invention may correspond to the position of each pixel of the sticker in the virtual container and fill the pixel point information of each pixel of the sticker in the corresponding position of the global two-dimensional array.

[0183] In this process, each pixel of the sticker can be traversed and the non-transparent pixels therein can be marked.

[0184] S405, counting the number of non-transparent pixels of the sticker in the overlapping area and the number of non-transparent pixels in the initial advertisement image.

[0185] S406, calculating the occlusion index.

[0186] Specifically, the method of calculating the occlusion index has been described in detail in the above embodiment and will not be repeated here.

[0187] S407, prompting the operator to perform an operation according to the occlusion index.

[0188] When the occlusion index is less than a preset threshold, the operator can be prompted that adding stickers at the current position will not block the main content of the advertising image. At this time, the final image can be generated, that is, the stickers are superimposed at the planned position in the initial advertising image to obtain the target advertising image.

[0189] When the occlusion index is not less than a preset threshold, the operator can be prompted to add stickers at the current position to prevent excessive occlusion of the main content of the advertisement image. The stickers can be adjusted by moving the position of the stickers, adjusting the size of the stickers, changing the type of stickers, etc.

[0190] The embodiment of the present invention applies the sticker adding method to the generation process of the advertising picture, which effectively improves the display effect of the advertising picture while ensuring that the main content of the advertising picture is not excessively covered by the sticker, thereby improving the effective communication rate of the advertisement.
