[0035] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0037] In order to enhance the aesthetic and artistic quality of images, adding special effects to images has become an important technical means. However, although some software or applications on the market currently provide the function of adding special effects, the types of special effects they provide are limited and cannot meet the diverse needs of users.

[0038] The technical solution provided by the disclosed embodiments is based on an original image, creating a background layer and a subject scan layer. The background layer includes a background area, while the subject scan layer includes a scanned object, which moves in a preset direction over time. As the scanned object moves, the subject is gradually revealed from nothing. The background layer and the subject scan layer are then merged to produce a processed image. Essentially, this method provides a method for automatically adding a new special effect to a target image. This special effect creates the visual effect of "printing" the subject object within the background image, meeting users' diverse needs for special effects and providing a richer visual experience.

[0039] FIG1 is a flowchart of an image processing method provided by an embodiment of the present disclosure. This embodiment is applicable to situations where image processing is performed on a client. The method can be executed by an image processing device, which can be implemented using software and / or hardware. The device can be configured in an electronic device, such as a terminal, including but not limited to smartphones, PDAs, tablet computers, wearable devices with displays, desktop computers, laptop computers, all-in-one computers, smart home devices, etc. Alternatively, this embodiment is applicable to situations where image processing is performed on a server. The method can be executed by an image processing device, which can be implemented using software and / or hardware. The device can be configured in an electronic device, such as a server.

[0040] As shown in FIG1 , the method may specifically include:

[0041] S110: Acquire an original image; the original image includes a main object.

[0042] The original image may be, for example, an image to which special effects are to be added. The original image may be specified by the user. Specifically, it may be an image captured by the user or an image downloaded from the Internet.

[0043] The object is the thing in the image, which can be a person, animal, plant, building or object.

[0044] The subject object may be, for example, an object in the original image that requires special attention or that is desired to be highlighted. This application does not limit the specific object to which the subject object refers. In some scenarios, the subject object may be the subject of the original image. For example, the subject object may be a person, an animal, a plant, a building, or an object. Furthermore, this application does not limit the number of subject objects. For example, the number of subject objects may be one, two, or three.

[0045] In the original image, the area occupied by the main object is the main area. The remaining area in the original image except the main area is the background area. The background area may or may not include the object.

[0046] Optionally, the original image may be, for example, a static image, a dynamic image, or an image frame in a video.

[0047] S120. Based on the original image, a background layer and a main scanning layer are obtained; the background layer includes a background area; the main scanning layer includes a scanning object, and the scanning object moves along a preset direction over time; during the movement of the scanning object, the main object is gradually revealed from nothing to something.

[0048] For example, the background layer can be a layer that only includes the background area image of the original image but does not include the main object. Figure 2 is a schematic diagram of an original image provided by an embodiment of the present disclosure. Figure 3 is a schematic diagram of the background layer obtained based on the original image provided in Figure 2. Referring to Figure 2, the original image includes a road and trees on both sides of the road, and a person is standing in the middle of the road. If the person is the main object, the road, trees on both sides of the road, and the sky constitute the image in the background area. Referring to Figure 3, the background layer obtained based on Figure 2 includes the background area image but does not include the main object.

[0049] The scanning object is used to characterize the position of the scan at the current moment. For example, it can be expressed in the form of a line, a shape, or the position of a combination of lines and / or shapes. The preset direction refers to a pre-specified direction. For example, the preset direction can be the direction from left to right, the direction from right to left, the direction from top to bottom, the direction from bottom to top, the direction from the middle to both sides, and the direction from both sides to the middle. In some original images, the depth information of each part of the main object is different. The depth information reflects the distance between the part represented by the pixel points that constitute the object and the camera. For this case, optionally, the preset direction can also be the direction of depth information from large to small, or the direction of depth information from small to large. In some scenarios, the preset direction can be specified by the user.

[0050] Figures 4-6 illustrate the subject scan layers at different times, based on the original image provided in Figure 2. Figure 4 corresponds to time T1, Figure 5 to time T2, and Figure 6 to time T3, with T1 occurring earlier than T2, which in turn occurs earlier than T3. Viewing Figures 4-6 sequentially creates the illusion that the target subject is gradually "printed" as the scanned object moves.

[0051] S130: Fusing the background layer and the subject scan layer to obtain a processed image.

[0052] Optionally, the subject scan layer is overlaid on the background layer to obtain a processed image.

[0053] For example, Figure 7 shows the effect of fusing the image in Figure 4 with the image in Figure 3, Figure 8 shows the effect of fusing the image in Figure 4 with the image in Figure 5, and Figure 9 shows the effect of fusing the image in Figure 4 with the image in Figure 6. Viewing Figures 7-9 sequentially, the background image is always displayed, but as the scanned object moves, the target subject is gradually "printed" into the background image.

[0054] The above technical solution creates a background layer and a subject scan layer based on the original image; the background layer includes the background area; the subject scan layer includes the scanned object, which moves in a preset direction over time. As the scanned object moves, the subject is gradually revealed from nothing. The background layer and the subject scan layer are then merged to produce a processed image. Essentially, this method provides a method for automatically adding a new special effect to a target image. This effect creates the visual effect of "printing" the subject object into the background layer, meeting users' diverse needs for special effects and providing a richer visual experience.

[0055] Based on the above technical solution, there are various methods for obtaining a background layer based on the original image, which are not limited in this application. For example, obtaining a background layer based on the original image may include: determining a subject area in the original image; the subject area is the area occupied by the subject object; removing the image in the subject area of ​​the original image; and filling the subject area in the original image with an image to obtain the background layer.

[0056] “Performing image filling on the subject area in the original image to obtain a background layer” may, for example, include: performing image filling on the subject area in the original image based on the image in the background area in the original image to obtain a background layer.

[0057] In some embodiments, based on the image in the background area of ​​the original image, the subject area in the original image is filled with an image, which can specifically include: using an image generation model to generate an image for the subject area in the original image based on the image in the background area. Optionally, the image generation model can be a generative adversarial model or an image diffusion generation model. In this way, the generated image for filling the subject area is related in content to the image in the background area of ​​the original image. Alternatively, an image restoration model can be used to restore the subject area in the original image based on the image in the background area. Optionally, the image restoration model can be a generative adversarial model or an image diffusion generation model. In this way, the restored image for filling the subject area is related in content to the image in the background area of ​​the original image, or there is no obvious color jump between the restored image for filling the subject area and the image in the background area of ​​the original image, and a natural transition can be achieved.

[0058] For example, comparing Figure 2 and Figure 3, in Figure 3, the area within the human wireframe is the subject area, and the area outside the human wireframe is the background area. The image in the subject area in Figure 3 is generated based on the image in the background area.

[0059] Based on the above technical solution, there are various specific implementation methods for "obtaining the main body scanning layer based on the original image", which are not limited by this application. For example, referring to FIG10 , the specific implementation method for obtaining the main body scanning layer based on the original image may include:

[0060] S210: Perform cutout processing on the main object in the original image to obtain a first layer.

[0061] Optionally, the first layer only includes the subject object and does not include the background area image. For example, FIG11 shows a schematic diagram of a first layer, which is obtained based on the original image provided in FIG2 .

[0062] S220. Determine a second layer, where the second layer includes a scanning object, and the scanning object moves along a preset direction over time; at any moment, the scanning object divides the second layer into a transparent area and a non-transparent area; during the movement of the scanning object, the range of the transparent area gradually changes, and the range of the non-transparent area gradually changes.

[0063] The second layer can be, for example, a preset layer that presents the effect of the scanned object moving over time. Specifically, the second layer is composed of multiple frames of images. The position of the scanned object is different in each frame of image. In each frame of image, the scanned object divides the entire area into a transparent area and a non-transparent area. If the frames of image are viewed continuously, the effect of the scanned object moving along a preset direction is presented, and the area and / or size of the transparent area and the non-transparent area change accordingly. Exemplarily, during the movement of the scanned object, the transparent area gradually increases and the non-transparent area gradually decreases; or, during the movement of the scanned object, the transparent area gradually decreases and the non-transparent area gradually increases.

[0064] The second layer is not associated with the main object in the original image. In other words, the position and size of the transparent area, as well as the position and size of the non-transparent area, are independent of the position and size of the main object in the original image.

[0065] For example, Figure 12 shows a schematic diagram of a frame image of the second layer. Referring to Figure 12 , the left side of the second layer is a non-transparent area, and the right side is a transparent area. The scanned object is located at the junction of the non-transparent and transparent areas. If the frames comprising the second image are viewed continuously, as the scanned object moves in the direction of the arrow over time, the non-transparent area gradually increases while the transparent area gradually decreases.

[0066] There are various methods for implementing S220, which are not limited in this application. For example, one method for implementing S220 may include: creating a transparent layer, creating an animation effect of an opaque color block scaling along a preset direction in the transparent layer; and modifying the edge of the opaque color block to obtain a second layer.

[0067] The animation effect of the opaque color block scaling along the preset direction may specifically be that the edge of the opaque color block gradually moves along the preset direction, and the opaque color block presents a visual effect of gradually expanding along the preset direction.

[0068] The edge of the opaque color block is modified to obtain a second layer. Specifically, at least one of the following operations may be performed on the opaque color block, and the resulting layer is used as the second layer: adding a rough edge effect to the edge of the opaque color block; displacing the opaque color block using a preset first noise image to distort the opaque color block; or adding a mosaic effect to the edge of the opaque color block. The purpose of modifying the edge of the opaque color block is to increase the sense of irregularity in the scan.

[0069] The first noise image may be, for example, a pre-specified noise image. The present application does not impose any limitation on the specific type of image the first noise image may be.

[0070] S230 . Based on the first layer, adjust the range of the transparent area and the non-transparent area in the second layer during the movement of the scanned object to obtain a third layer, so that the non-transparent area in the third layer is associated with the main object.

[0071] “The non-transparent area is associated with the main object” may, for example, mean that if the first layer and the third layer are overlapped, the non-transparent area overlaps with at least a portion of the main object.

[0072] There are many specific implementation methods for S230, which are not limited in this application. For example, the implementation method of this step may include: overlaying the second layer as a transparent mask on the first layer; for pixels that are opaque in the second layer and opaque in the first layer, setting their transparency channels to opaque; for pixels that are opaque in the second layer but transparent in the first layer, and pixels that are transparent in the second layer but opaque in the first layer, setting their transparency channels to transparent, thereby obtaining a third layer. This allows the non-transparent areas in the third layer to be associated with the main object.

[0073] Figures 13-15 are schematic diagrams of a third layer provided by an embodiment of the present disclosure at different times. Figure 13 corresponds to time T1, Figure 14 corresponds to time T2, and Figure 15 corresponds to time T3, with T1 occurring earlier than T2, and T2 occurring earlier than T3. When viewing Figures 13-15 sequentially, the entire third layer initially appears transparent. As the scanned object moves, the area occupied by the subject (i.e., the non-transparent area) gradually changes to a non-transparent area along a predetermined direction.

[0074] S240: Merge the first layer and the third layer to obtain a main scanning layer.

[0075] Optionally, a third layer can be overlaid on the first layer to create a main scan layer. The main scan layer includes transparent and non-transparent areas. The transparent areas allow the background image to show through after the main scan layer is fused with the background layer. The non-transparent areas create the visual effect of the main object gradually being printed out after the main scan layer is fused with the background layer.

[0076] Based on the above technical solution, optionally, after S230, the process further includes: creating a fourth layer based on the third layer, the fourth layer including a modification object for modifying the scanned object; the modification object moving in a preset direction over time; and the movement speed of the modification object being consistent with the movement speed of the scanned object; and S240 including: fusing the first layer, the third layer, and the fourth layer to obtain the main scan layer. The modification object is used to depict and render the scanned object, and can present a specific visual effect, making the final processed image more interesting and artistic. For example, the modification object is used to add a colorful luminous effect to the scanned object.

[0077] In practice, the specific production method of the fourth layer varies depending on the desired visual effect. For example, if the third layer includes N frames of images, producing the fourth layer based on the third layer includes: duplicating the third layer to obtain a fifth layer; setting t = 1, repeatedly performing the following modification object production steps until t = Na, obtaining a modification object image corresponding to the image in the third layer; processing the modification object image corresponding to the image in the third layer into the fourth layer; the modification object production steps include: determining the modification object image corresponding to the tth frame image of the third layer based on the t+ath frame image of the fifth layer and the tth frame image of the third layer; updating the value of t so that the difference between the updated value of t and the value of t before the update is 1; wherein t and a are both positive integers, and a≤N-1.

[0078] Furthermore, a t+a-th frame image based on the fifth layer and the t-th frame image of the third layer can be set to determine the modified object image corresponding to the t-th frame image of the third layer, including: subtracting the t+a-th frame image of the fifth layer and the t-th frame image of the third layer to obtain the modified object image corresponding to the t-th frame image of the third layer.

[0079] For example, referring to FIG16 , the fifth layer is a copy of the third layer, so the first frame image of the fifth layer is identical to the first frame image of the third layer. The second frame image of the fifth layer is identical to the second frame image of the third layer, and so on. If a = 2, the modified image corresponding to the first frame image of the third layer is the difference between the third frame image of the fifth layer (i.e., the third frame image of the third layer) and the first frame image of the third layer; the modified image corresponding to the second frame image of the third layer is the difference between the fourth frame image of the fifth layer (i.e., the fourth frame image of the third layer) and the second frame image of the third layer; the modified image corresponding to the third frame image is the difference between the fifth frame image of the fifth layer (i.e., the fifth frame image of the third layer) and the third frame image of the third layer, and so on. Using the above method, the modified image corresponding to FIG13 is shown in FIG17 , the modified image corresponding to FIG14 is shown in FIG18 , and the modified image corresponding to FIG15 is shown in FIG19 .

[0080] Optionally, fusing the first layer, the third layer, and the fourth layer to obtain the main scanning layer includes: fusing the first layer, the third layer, and the fourth layer in the order of the fourth layer, the third layer, and the first layer to obtain the main scanning layer.

[0081] Furthermore, after processing the modified object image corresponding to the image in the third layer into the fourth layer, the method includes: adjusting the modified object in the fourth layer so that the modified object presents a colorful luminous effect.

[0082] Specifically, adjusting the modified object in the fourth layer may include, for example, performing at least one of the following steps: multiplying the fourth layer with the second preset noise image to increase the brightness difference of the pixels in the fourth layer; adding sharpening and / or chromatic aberration effects to the modified object in the fourth layer so that the modified object has the visual effect of a grid edge; adjusting the color of the modified object based on a preset color mapping relationship so that the modified object appears in color; and adding a luminous effect to the modified object.

[0083] The second preset noise image is a pre-specified noise image, and the present application does not limit what kind of noise image the second preset noise image specifically refers to. The second preset noise image can be the same as or different from the first preset noise image.

[0084] For example, the fourth layer can be multiplied with the second preset noise image; then, sharpening and chromatic aberration effects can be added to the modified object in the resulting image; then, based on a preset color mapping relationship, the color of the modified object with sharpening and chromatic aberration effects can be adjusted; and finally, a glowing effect can be added to the modified object. This can make the modified object appear to be shining with colorful light, creating a magical atmosphere of flowing light objects.
