[0043] As Figure 1 shown, the method includes:

[0044] S110. Generate a plurality of line entities based on the set special effect attribute information.

[0045] Among them, the embodiments of the present disclosure can be executed by a special effect editing tool. The set special effect attribute information can be the number of lines set by the user or predefined by the tool in advance. A line entity can be understood as a container for editing a line graph and can hold multiple components related to the line graph. The line entity can be generated by running an edited program script based on the set special effect attribute information.

[0046] In the embodiments of the present disclosure, when the user enters the special effect editing tool, the set special effect attribute information is input in the panel of the special effect editing tool, and the special effect editing tool runs the edited program script to generate a plurality of line entities. The number of line entities is related to the number of generated line layers.

[0047] In the embodiments of the present disclosure, optionally, generating a plurality of line entities based on the set special effect attribute information includes: generating a plurality of empty entities based on the set special effect attribute information; respectively adding the set components to the plurality of empty entities to obtain a plurality of line entities; where the set components include a position component, a mesh rendering component, and a script component, and the script component is mounted with a set special effect script.

[0048] Among them, an empty entity can be understood as a container to which set components can be added. The plurality of line entities can be obtained by adding the set components to a plurality of empty entity containers. The set components can be components configured with initial parameters and can be configured according to actual needs. In this embodiment, the set components can include components such as a position component (transform), a mesh rendering component (meshrenderer), and a script component (scriptcomponent). The position component can be understood as a component including position coordinate parameters and is used to determine the position of the line in the world. The mesh rendering component can be understood as a component including mesh parameters (mesh) and material parameters (material). The script component can be used to mount the set special effect script.

[0049] In the embodiments of the present disclosure, optionally, respectively adding the set components to the plurality of empty entities to obtain line entities includes: running the set special effect script to obtain set special effect parameters; and configuring the set special effect parameters in the position component and the mesh rendering component to obtain a plurality of line entities.

[0050] Among them, the set special effect script can be understood as the underlying code called, which can be pre-edited. The set special effect parameters can be understood as the special effect parameters obtained by running the set special effect script mounted in the script component, and can be used to configure the position component and the mesh rendering component. In the embodiments of the present disclosure, the special effect editing tool can obtain a plurality of line entities by configuring the set special effect parameters in the position component and the mesh rendering component.

[0051] In the embodiments of the present disclosure, the special effect editing tool generates a plurality of empty entities based on the set special effect attributes; adds set components such as the position component, the mesh rendering component, and the script component to the plurality of empty entities respectively, so as to obtain a plurality of line entities; runs the set special effect script mounted in the script component to obtain the set special effect parameters. Run the set special effect script to obtain the set special effect parameters, and configure the set special effect parameters in the position component and the network rendering component, so as to obtain a plurality of line entities. Through such settings in the embodiments of the present disclosure, a plurality of line entities can be generated based on the set special effect attribute information, so as to facilitate the setting of multiple lines of the "multi-layer stroke" special effect for the image.

[0052] Exemplarily, an example diagram of the generation interface of a plurality of line entities is as Figure 2 shown. On the left, it can be understood as a plurality of line entities such as line entity 1, line entity 2, line entity 3, and line entity 4. The right interface can be understood as the settings of various set components, which can be set according to the actual needs of the user.

[0053] In the embodiments of the present disclosure, optionally, the method further includes: after running the set special effect script, it further includes:

[0054] Generating a line attribute panel corresponding to the set special effect script.

[0055] Among them, the line attribute panel can be a panel interface for setting line attribute information; the line attribute panel can be generated corresponding to running the set special effect script. Specifically, the line attribute panel can set attributes such as line width, line color, line transparency, set special effect material, and position change. In the embodiments of the present disclosure, the special effect editing tool can run the set special effect script to generate a line attribute panel, which is beneficial for users to set line attribute information and improves the flexibility of editing.

[0056] S120. Receive the line attribute information set by the user in one or more of the plurality of line entities.

[0057] Among them, the line attribute information may include at least one of the following: line width, line color, line transparency, set special effect material, and position transformation. In the embodiments of the present disclosure, one or more line attribute information can be set in multiple line entities. It can be understood that the line width is the specific width value of the line. The line color can be colors such as red, blue, yellow, and green, which can be set according to the actual needs of the user and are not limited here. The line transparency is the transparency value of the line, which can be set according to the actual needs of the user. For example, when the line transparency value is set to 0, the line is not displayed; when the transparency value is 1, the line is fully displayed. The set special effect material may include a set ordinary material and a glow material; the set special effect material may also include a material color and a material transparency. In this embodiment, a switch of "glow material" can be set in the line attribute panel. If the user turns on this switch, it indicates that the glow material is selected. If this switch is turned off, it indicates that the ordinary material is selected. The position transformation information may include at least one of the following: translation information, rotation information, scaling information, and flipping information. Exemplarily, the position transformation may be position transformations such as translation to the left, translation to the right, scaling of the size, and horizontal and vertical flipping.

[0058] In the embodiments of the present disclosure, the special effect editing tool can receive one or more line attribute information such as line width, line color, line transparency, set special effect material, and position transformation set by the user in multiple line entities respectively.

[0059] Optionally, the process of receiving the line attribute information set by the user in the multiple line entities may be: receiving the line attribute information input by the user through the line attribute panel.

[0060] Among them, the line attribute panel can be a panel interface for setting line attribute information. The line attribute information can be the information input by the user through the line attribute panel and can be input according to the user's needs. In the embodiments of the present disclosure, the special effect editing tool can receive the line attribute information input by the user through the line attribute panel. Through such a setting in the embodiments of the present disclosure, the line attribute information can be input and set according to the actual needs of the user, which is more flexible.

[0061] S130. Generate multiple layers of special effect lines in a preset order based on the line attribute information and the obtained segmentation mask image. Among them, the segmentation mask image is obtained by segmenting the target object in the original image;

[0062] Among them, the segmentation mask image can be understood as an image obtained by segmenting the target object in the original image. The original image can be understood as the original image corresponding to the segmentation mask processing operation of the image. The target object can be understood as the target area to be segmented in the original image. Exemplarily, Figure 3is an example diagram of a segmentation mask image obtained by an embodiment of the present disclosure, such as Figure 3 As shown, the segmentation mask image is a mask image obtained by segmenting a human portrait. In this embodiment, there is no limitation on the segmentation object in the segmentation mask image, for example, it can be: animals, plants or buildings.

[0063] The preset order can be set by the user or can be random, the order of multiple line entities from inside to outside or from outside to inside, and is exemplarily sorted in the order of generated line entities. The order of line entities can determine the order of generating special effect lines and the hierarchical order of lines. The special effect lines corresponding to the front line entities are generated first and at a higher level. Multi-layer special effect lines can be understood as multiple special effect lines displayed in a hierarchical relationship.

[0064] In the embodiment of the present disclosure, the special effects editing tool can generate multiple layers of special effects lines in sequence according to the order of multiple line entities based on the line attribute information and the acquired segmentation mask image.

[0065] S140: superimpose the multiple layers of special effect lines onto the original image to obtain a special effect image.

[0066] The original image can be understood as the original image corresponding to the segmentation mask processing operation. The special effect image can be understood as the special effect image obtained by superimposing multiple layers of special effect lines on the original image corresponding to the segmentation mask image.

[0067] In the disclosed embodiment, the special effects editing tool superimposes multiple layers of special effects lines onto the original image corresponding to the segmentation mask image, thereby obtaining a special effects image.

[0068] The technical solution of the disclosed embodiment generates multiple line entities based on set special effect attribute information; receives line attribute information set by a user for one or more of the multiple line entities; generates multiple layers of special effect lines in a preset order based on the line attribute information and the acquired segmentation mask map; wherein the segmentation mask map is obtained by segmenting the target object in the original image; and superimposes the multiple layers of special effect lines on the original image to obtain a special effect map. This technical solution can generate an image with a "multi-layer stroke" special effect, thereby improving the richness of image display.

[0069] Figure 4A flowchart of another special effect generation method provided by an embodiment of the present disclosure; this embodiment is optimized based on the optional solutions provided in the above embodiments. Specifically, the optimization is as follows: generating multiple layers of special effect lines in a preset order based on the line attribute information and the obtained segmentation mask image, including: for each layer of special effect lines, determining an edge extraction step size based on the line width; performing edge extraction on the segmentation mask image according to the edge extraction step size to obtain an edge line mask image; generating special effect lines based on at least one of line color, line transparency, set special effect material, and position transformation information and the edge line mask image.

[0070] As Figure 4 shown, the method includes:

[0071] S410. Generate a plurality of line entities based on set special effect attribute information.

[0072] S420. Receive line attribute information set by a user for one or more of the plurality of line entities.

[0073] S430. For each layer of special effect lines, determine an edge extraction step size based on the line width.

[0074] Among them, there can be multiple layers of special effect lines, and different settings can be made for each layer of special effect lines according to user requirements. The edge extraction step size can be extracted using any edge extraction algorithm. The edge extraction step size can be determined based on the line width and can be obtained by multiplying the line width by a preset set coefficient (for example: 0.01) to obtain the corresponding edge extraction step size. In the embodiment of the present disclosure, for each layer of special effect lines, the special effect editing tool can determine the edge extraction step size based on the line width.

[0075] S440. Perform edge extraction on the segmentation mask image according to the edge extraction step size to obtain an edge line mask image.

[0076] Among them, the edge line mask image can be understood as an image obtained by performing edge extraction on the segmentation mask image according to the edge extraction step size. In the embodiment of the present disclosure, the Laplace edge extraction algorithm can be used to perform edge extraction on the segmentation mask image according to the edge extraction step size to obtain the edge line mask image. Exemplarily, in the embodiment of the present disclosure, the edge calculated by the four-neighborhood Laplace algorithm using different step sizes can be used, and an example diagram of the edge line mask image is as Figure 5 shown.

[0077] S450. Generate special effect lines based on at least one of line color, line transparency, set special effect material, and position transformation information and the edge line mask image.

[0078] Among them, the special effect line can be generated based on at least one of line color, line transparency, set special effect material, and position transformation information, as well as the edge line mask image.

[0079] Exemplarily, the special effect line in the embodiments of the present disclosure can be a special effect line generated based on line color, line transparency, and the edge line mask image; it can also be a special effect line generated based on the set special effect material and the edge line mask image; it can also be a special effect line generated based on line color, position transformation information, and the edge line mask image; the required information can be set according to the actual needs of the user to generate the special effect line. Through such a setting in the embodiments of the present disclosure, different settings can be made for each layer of special effect line according to the user's needs, so as to generate an image with a "multi-layer stroke" special effect, further improving the richness of image display.

[0080] S460. Superimpose the multi-layer special effect line onto the original image to obtain a special effect image.

[0081] In the embodiments of the present disclosure, optionally, the segmentation mask image includes a target object area and a background area; the method of determining the edge extraction step size based on the line width can be: determining a first edge extraction step size and a second edge extraction step size based on the line width; the method of obtaining the edge line mask image by performing edge extraction on the segmentation mask image according to the edge extraction step size can be: performing edge extraction on the target object area according to the first edge extraction step size, and performing edge extraction on the background area according to the second edge extraction step size to obtain the edge line mask image.

[0082] Among them, the segmentation mask image can include a target object area and a background area. The target object area can be understood as the area where the segmented target object is located, such as Figure 3 the portrait area in. The background area can be understood as the area other than the target object area. The first edge extraction step size and the second edge extraction step size can be determined based on the line width, and can be understood as the edge extraction step sizes for the inner and outer sides of the segmentation mask image respectively. In the embodiments of the present disclosure, the first edge extraction step size can be used to perform edge extraction on the target object area; the second edge extraction step size can be used to perform edge extraction on the background area.

[0083] Specifically, the first edge extraction step size and the second edge extraction step size can be obtained by multiplying the line width by a set coefficient; among them, the set coefficient can be set according to the actually extracted step size. Exemplarily, the set coefficient can be set to coefficients such as 0.01, 0.02, and 0.03. The first edge extraction step size and the second edge extraction step size are not equal.

[0084] In the embodiments of the present disclosure, the first edge extraction step size and the second edge extraction step size can be determined based on the line width; the edge of the target object area is extracted according to the first edge extraction step size, and the edge of the background area is extracted according to the second edge extraction step size, so as to obtain an edge line mask map. Through such a setting in the embodiments of the present disclosure, different edge step sizes can be extracted for the target object area and the background area according to actual needs, which can improve the display effect.

[0085] In the embodiments of the present disclosure, optionally, the method for generating a special effect line based on the line color and the edge line mask map may be: fusing the color value of the line color with the pixel value of the pixel point in the edge line mask map to obtain the target color of the special effect line; performing line rendering based on the target color to obtain the special effect line.

[0086] Among them, the color value may be the RGB value of the line color. For example, it may include the corresponding color values of red, green, and blue. The line color in the embodiments of the present disclosure can be a color input by the user according to personal needs. The pixel value may be the pixel value corresponding to the pixel point in the edge line mask map; exemplarily, it may be a value between 0 and 1. The edge mask map may be represented by black and white. If it is a black area, the pixel value corresponding to the pixel point is 0; if it is a white area, the pixel value corresponding to the pixel point is 1.

[0087] In the embodiments of the present disclosure, fusing the color value of the line color with the pixel value of the pixel point in the edge line mask map can be understood as multiplying the color value of the line color by the pixel value of the pixel point in the edge mask map to obtain a value. The target color may be the color obtained by multiplying the color value of the line color by the pixel value of the pixel point in the edge line mask map. The special effect line can be understood as the special effect line obtained by rendering the line based on the target color, so that the special effect line displays the target color.

[0088] In the embodiments of the present disclosure, the target color of the special effect line can be obtained by multiplying the color value of the line color by the pixel value of the pixel point in the edge line mask map; and line rendering is performed based on the target color, so as to obtain the special effect line. Through such a setting in the embodiments of the present disclosure, a special effect line can be generated according to the line color in the line attributes and the edge line mask map.

[0089] In the embodiments of the present disclosure, optionally, generating a special effect line based on the line transparency and the edge line mask map includes: performing a blur process on the edge line mask map to obtain a blurred line mask map; fusing the line transparency value with the pixel value of the pixel point in the blurred line mask map to obtain the target transparency; performing line rendering based on the target transparency to obtain the special effect line.

[0090] Among them, the blurring process can be understood as performing mean blurring (e.g., mean blurring process of 7*7) or Gaussian blurring on the edge pre-mask image, etc., which is not limited here. Optionally, in this embodiment, mean blurring process is adopted. The principle of mean blurring is to calculate the average value of a pixel and its surrounding pixels through a graphic filter. The blurred line mask image can be a blurred line mask image obtained by blurring the edge line mask image. The line transparency value can be obtained according to the set transparency value (which can also be called the feathering value). The line transparency value can be input by the user according to personal actual needs.

[0091] Optionally, fusing the line transparency value with the pixel value of the pixel point in the blurred line mask image to obtain the target transparency includes: if the line transparency value is within the first set range, fusing the line transparency value with the pixel value of the pixel point in the blurred line mask image based on the first set value to obtain the target transparency; if the line transparency value is within the second set range, fusing the line transparency value with the pixel value of the pixel point in the blurred line mask image based on the second set value to obtain the target transparency.

[0092] Among them, the first set range can be the range from -1 to 0, and the first set value can be 1. When the line transparency value x is within the first set range from -1 to 0, fuse the line transparency value with the pixel value of the pixel point in the blurred line mask image based on the first set value. That is, when the line transparency value x input by the user is within the first set range, the line transparency value and the pixel value of the pixel point in the blurred line mask image are fused using the formula y=(x + 1)*r - x*1.0, where x represents the feathering value of the line transparency, r represents the pixel value of the pixel point in the blurred line mask image, and y represents the target transparency value. The second set range can be the numerical range from 0 to 1, and the second set value can be 0. When the line transparency value x input by the user is within the second set range, the line transparency value and the pixel value of the pixel point in the blurred line mask image are calculated using the following formula: y=(1.0 - x)*r.

[0093] In the embodiment of the present disclosure, a blurred line mask image can be obtained by blurring the edge line mask image; the line transparency value and the pixel value of the pixel point in the blurred line mask image are fused in different set values according to the set range to obtain the target transparency; based on the target transparency, line rendering is performed to obtain a special effect line, which can make the generated special effect line present a "feathering" effect.

[0094] In an embodiment of the present disclosure, optionally, the set special effect material includes a material color and a material transparency. Generating a special effect line based on the set special effect material and the edge line mask image includes: fusing the material color value with the pixel value of the pixel point in the edge line mask image to obtain a target material color value; blurring the segmentation mask image to obtain a blurred segmentation mask image; fusing the material transparency value with the pixel value of the pixel point in the blurred segmentation mask image to obtain a target material transparency value; performing line rendering based on the target material color value and the target material transparency value to obtain a special effect line.

[0095] Among them, the set special effect material may include a material color and a material transparency. The target material color value can be obtained by fusing the material color value with the pixel value of the pixel point in the edge line mask image. Specifically, the target material color value can be obtained by multiplying the material color value with the pixel value of the pixel point in the edge line mask image. The blurred segmentation mask image can be obtained by blurring the segmentation mask image. Exemplarily, an example diagram of the blurred segmentation mask image obtained by blurring the segmentation mask image is as Figure 6 shown.

[0096] In an embodiment of the present disclosure, optionally, fusing the material transparency value with the pixel value of the pixel point in the blurred segmentation mask image to obtain a target material transparency value includes: linearly superimposing the material transparency value with the pixel value of the corresponding pixel point in the blurred segmentation mask image to obtain a first intermediate transparency value; performing a set exponential operation on the first intermediate transparency value to obtain a second intermediate transparency value; performing a linear transformation on the second intermediate transparency value to obtain a target material transparency value.

[0097] Among them, the first intermediate transparency value can be obtained by linearly superimposing the material transparency value with the pixel value of the corresponding pixel point in the blurred segmentation mask image. Specifically, when the pixel value of the corresponding pixel point in the blurred segmentation mask image is greater than 0.5, the first intermediate transparency value can be determined by the following formula: y1 = clamp(0.5, 1, R + 0.5 - L * 0.5), where L represents the material transparency value, R represents the pixel value of the corresponding pixel point in the blurred segmentation mask image, y1 represents the first intermediate transparency value, and the clamp() function represents restricting the value of R + 0.5 - L * 0.5 between 0.5 and 1. When the pixel value of the corresponding pixel point in the blurred segmentation mask image is less than 0.5, the first intermediate transparency value can be determined by the following formula: y1 = (0, 0.5, R - 0.5 + L * 0.5), where L represents the material transparency value, R represents the pixel value of the corresponding pixel point in the blurred segmentation mask image, y1 represents the first intermediate transparency value, and the clamp() function represents restricting the value of R + 0.5 - L * 0.5 between 0 and 0.5.

[0098] Among them, the set exponential operation can be an exponential operation for setting the first intermediate transparency value. Other power setting exponential operations such as squaring or cubing the first intermediate transparency value can be set, and can be set according to actual needs. The set exponential operation for the first intermediate transparency value can adopt the following formula: y2 = [(0.5 - y1) * 2]^2, where y2 represents the second intermediate transparency value. The target material transparency value can be obtained by linearly transforming the second intermediate transparency value. Specifically, the linear transformation of the second intermediate transparency value can adopt the following formula: Y = 1 - y2, that is, a linear transformation obtained by subtracting 1.0 from the second intermediate transparency value.
