Description

TECHNICAL FIELD

[0001] The present application relates to the field of image processing, in particular to an image processing method and device, a storage medium and an electronic device. BACKGROUND

[0002] With the rapid development of life and technology, people often entertain themselves through game applications. In game production, a large number of mask images are often used to achieve various game effects. In the development process of a shader, a point operator is generally used to read a mask texture. A single channel mask image is read fixedly at a time, or a mask image is read in the form of a black and white image or an alpha image.

[0003] In the research and practice of the prior art, it is found that if the point operator is used to read the mask image, conditional judgment (if) statements need to be added to control the selection of multiple channels respectively, thereby increasing the Shader branches and reducing the rendering performance. If the mask image is read in the form of a black and white image or an alpha image, the amount of picture resources required will be doubled, which reduces the game performance. It can be seen that the reading efficiency of the mask image is low in the existing image processing method. SUMMARY

[0030] The scheme provided by the embodiment of the present application is described in detail by the following embodiments. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments.

[0031] This embodiment will be described from the perspective of an image processing device, which can be integrated in an electronic device. The electronic device can be a terminal and / or a server, which is not limited in the present application.

[0032] Referring to Figure 2 , Figure 2 is a flowchart of the image processing method provided by the embodiment of the present application. The image processing method comprises:

[0033] In step 101, mask image reading information for a target texture image is acquired.

[0034] The target texture image can include mask images on multiple color channels.

[0035] The target texture image can be an image in which mask images are stored on color channels. The color channels can be channels in which color information of an image is stored. The color channels of an image can be different in different color modes. For example, in an RGB color mode, the color channels of the target texture image can include a red (R) channel, a green (G) channel, and a blue (B) channel. The mask image can be a mask type image, which can be used to control or limit a display range of certain effects in a rendering process, or to adjust a display effect of certain rendering effects.

[0036] Optionally, a mask image can be stored on each color channel of the target texture image, so that multiple mask images can be combined into one texture image, reducing the amount of picture resources required by a game, thereby reducing the download time of game data for a user and improving the running efficiency of the game.

[0037] For example, referring to Figure 3 , Figure 3 is a layer superimposition diagram of an image processing method provided by an embodiment of the present application. It is assumed that the color channels include an R channel, a G channel, and a B channel. Three black and white mask images can be acquired, and the three mask images can be stored in the R channel, the G channel, and the B channel of an image respectively, so that a single RGBA image (or RGB image) can be obtained, that is, a target texture image. The single image can include information of the three mask images.

[0038] Optionally, before the mask image reading information for the target texture image is acquired, a mask reading parameter can be set in a target buffer. The mask reading parameter is configured as an integer type, and a value range of the mask reading parameter belongs to a value range corresponding to an array element index of a mask texture array corresponding to the target texture image. The mask image reading information input for the target texture image is received, and the mask image reading information is assigned to the mask reading parameter.

[0039] Correspondingly, the step of acquiring the mask image reading information for the target texture image can include reading a parameter value of the mask reading parameter in the target buffer to obtain the mask image reading information for the target texture image.

[0040] The target buffer can be a buffer for storing the mask map reading information corresponding to the target texture image. For example, the target buffer can be a constant buffer, which can be used to store constant data in a shader program. The constant buffer can be declared by a constant buffer keyword (cbuffer), which is a keyword in a High-Level Shading Language (HLSL) for defining a constant buffer. The HLSL is a programming language for shaders. The mask reading parameter can be a parameter for obtaining the mask map reading information, the mask reading parameter is configured as an integer type (IntSlider), and the value range of the mask reading parameter belongs to the value range of the array element index of the mask texture array corresponding to the target texture image. The mask texture array can be an array for storing the mask maps of each color channel in the target texture image. The mask map of each color channel is an array element in the mask texture array. The array element can be an element in the mask texture array. The array element index can be an array index corresponding to the element in the mask texture array. The index can be a number for locating and accessing a specific element in an array. Any element in the array can be directly accessed or modified by the index. For example, assuming that the mask texture array stores the mask maps of the R channel, the G channel, and the B channel of the target texture image in sequence, the array element index corresponding to the R channel in the mask texture array corresponding to the target texture image can be 0, the array element index corresponding to the G channel can be 1, and the array element index corresponding to the B channel can be 2. In this way, the value range of the mask reading parameter belongs to the value range of the array element index of the mask texture array, that is, the value range [0, 2] corresponding to 0 to 2, that is, the value of the mask reading parameter can include 0, 1, or 2.

[0041] The parameter value of the mask reading parameter in the target buffer can be obtained in various ways. For example, the mask map reading information for the target texture image can be obtained in the target buffer by a target shader associated with the target buffer.

[0042] The target shader can be a shader associated with the target buffer. For example, the target shader can be bound to the target buffer, or the target buffer can be defined in the shader code, so that the target shader can obtain the data in the target buffer.

[0043] Optionally, data that can be changed in the game editing process can be stored in the target buffer cbuffer, which can be transmitted to the graphics processor GPU and used in the vertex shader or the pixel shader. Among these parameters, an integer parameter (int parameter) can be placed, that is, a mask reading parameter, which is transmitted to the index bracket [] of the code reading the texture channel to confirm which color channel of the target texture image needs to be read. This setting can be used to set the rendering state of the Shader, and finally used for rendering of the game picture.

[0044] In an embodiment, the mask reading parameter can be set as an integer parameter in the cbuffer, and the range and step of the value of the user input mask reading parameter can be clamped to ensure that the value corresponding to the user input mask reading parameter corresponds to the value corresponding to the array element index of the mask texture array corresponding to the target texture image. Otherwise, the mask texture array stored in the mask texture array cannot be positioned according to the information read from the mask image, and invalid values are avoided. Therefore, the array index method for the target texture image can be used to determine the parameter value of the mask reading parameter by filling the integer type mask reading information in the index box by the user, and the channel information corresponding to each mask picture in the target texture image can be obtained by transmitting the integer parameter value.

[0045] For example, assuming that the array element index of the mask texture array corresponding to the target texture image includes 0, 1, and 2, the following code can be used to set the mask reading parameter in the target buffer, and the mask reading parameter is configured as an integer type and the value range belongs to the value range corresponding to the array element index of the mask texture array corresponding to the target texture image:

[0046] int parameter<Widget="IntSl ider";Min="0";Max="2";Step="1";

[0047] Precis ion="0";>=0

[0048] Wherein, parameter can represent the mask reading parameter, IntSl ider can represent the integer type, Min can represent the minimum value in the value range of the mask reading parameter, that is, 0, Max can represent the maximum value in the value range of the mask reading parameter, that is, 2, and Step can represent the step in the value range of the mask reading parameter. Therefore, the mask reading parameter in the target buffer can be configured as an integer type, and the value range belongs to the value range corresponding to the array element index of the mask texture array corresponding to the target texture image (0, 1, and 2).

[0049] In an embodiment, a plurality of mask images can be stored in a plurality of color channels in the same image to obtain a target texture image. For example, at least two mask images can be obtained; color channels corresponding to the mask images are determined; color settings are performed on the mask images corresponding to the color channels based on color values of the color channels, to obtain set mask images; and the set mask images are combined to obtain the target texture image.

[0050] The color values corresponding to the color channels can be color values set for the color channels. For example, when a mask image corresponds to an R channel, the color value corresponding to the mask image can be a color value a of the R channel and color values 0 of other channels. For another example, when a mask image corresponds to a G channel, the color value corresponding to the mask image can be a color value b of the G channel and color values 0 of other channels. For another example, when a mask image corresponds to a B channel, the color value corresponding to the mask image can be a color value c of the B channel and color values 0 of other channels. The values of a, b, and c can be preset color values, such as 100, 200, 255, or the like. The values of a, b, and c can be the same or different, and the specific values can be set according to actual conditions, which are not limited in the embodiments of the present application. The set mask image can be a mask image after color setting. For each set mask image, the color value on the corresponding color channel is not 0, and the values on other color channels are 0.

[0051] The set mask images can be combined in various ways to obtain the target texture image. For example, a mixing order of the color channels in a target superimposition mode can be determined; and the set mask images are subjected to layer superimposition processing based on the mixing order to obtain the target texture image.

[0052] The target superimposition mode can be a mode of combining the set mask images, such as a screen mode. The mixing order can be an order of layer superimposition of the mask images corresponding to the color channels.

[0053] The set mask images can be combined in various ways to obtain the target texture image. For example, a mixing order of the color channels in a target superimposition mode can be determined; and the set mask images are subjected to layer superimposition processing based on the mixing order to obtain the target texture image.

[0054] For example, to meet the rendering needs of a game, three black and white mask images can be created in graphics and video processing software (After Effects, AE). Areas with an alpha of 1 correspond to white, and areas with an alpha of 0 correspond to black. The three mask images can be overlapped. Then, using the software's coloring function, each mask image can be colored according to its corresponding color channel. For example, the mask image corresponding to the red channel can be colored red, the mask image corresponding to the green channel can be colored green, and the mask image corresponding to the blue channel can be colored blue, etc. This allows the overlay mode of all three mask images to be set to the target overlay mode (Screen). When calculating color values, the color values ​​of each mask image need to be normalized. Finally, the three overlaid mask images can be exported as a single image to obtain the target texture image.

[0055] The Screen blending mode is a layer blending mode that creates an effect similar to the overlay projection of two slides. The formula for calculating the Screen blending mode value is: Output = 1 - (1 - Top) * (1 - Bottom), where Output represents the color value of the overlaid layers, and Top and Bottom represent the color values ​​of the upper and lower layers (between 0 and 1), respectively. When using Screen mode to overlay mask images from the red, green, and blue channels, this formula allows for the blending of color values ​​from each mask image on the same color channel, resulting in the overlaid color value. This produces an image containing complete RGB information because in Screen mode, each color channel is calculated independently. For example, if a color channel has a value of 1 in the upper image (meaning it's the brightest), then regardless of the lower image's value in that color channel, the output image will also have a value of 1. Therefore, the color values ​​of each RGB channel can be extracted from the merged target texture image.

[0056] In step 102, the target array element index for the mask texture array is determined based on the mask image reading information.

[0057] One array element in the mask texture array corresponds to the mask image of the target texture image on one color channel.

[0058] The mask texture array can be an array storing mask images on each color channel of a target texture image, and the mask images on each color channel of the target texture image are array elements of the mask texture array. Each array element has a corresponding array element index, and each mask image on a color channel of the target texture image corresponds to an array element index. The array element index can be the subscript of the array element in the mask texture array. The target array element index can be the array element index corresponding to the mask image reading information. An array is a composite data type composed of a series of elements of the same type, and the storage space of the elements in the array can be adjacent.

[0059] The target array element index of the mask texture array can be determined in various ways according to the mask image reading information. For example, the mask image reading information can be a numerical value, and the mask image reading information can be determined as the target array element index of the mask texture array corresponding to the target texture image.

[0060] For example, the mask image reading information can be a numerical value corresponding to the array element index of the mask texture array, so that the corresponding target array element index can be determined in the array element index of the mask texture array according to the mask image reading information.

[0061] Optionally, the mask texture array corresponding to the target texture image can be obtained in various ways. For example, the target texture image can be obtained, the mask images on each color channel of the target texture image can be read, and the mask images on each color channel can be stored as an array element in the mask texture array, and each array element can be set with a corresponding array element index, wherein the array element indexes corresponding to different color channels are different.

[0062] The mask images on each color channel of the target texture image can be read and stored as an array element in the mask texture array in various ways. For example, a mask texture array containing a plurality of array elements can be set, and the number of array elements is consistent with the number of color channels of the target texture image. The target texture image can be sampled based on the sampling coordinates corresponding to the target texture image. The sampling color information corresponding to the mask image of each color channel can be obtained according to the sampling result. The sampling color information of the mask image on each color channel can be written into an array element of the mask texture array.

[0063] The sampling coordinates can be coordinates for texture sampling of the target texture image, which can be UV coordinates, the UV coordinates can be coordinates in a two-dimensional coordinate system, used for mapping a texture map to the surface of a three-dimensional model, and U and V can represent horizontal and vertical coordinate axes respectively. The UV coordinates can define information about the position of each point on the texture map, which is related to the three-dimensional model, so as to correspond each point on the texture map to the surface of the model. The sampling result can be a result of sampling the target texture image according to the sampling coordinates corresponding to the target texture image. The sampling color information can be color values sampled on the mask map of each color channel. For example, after storing the target texture image in the game engine directory, the target texture image can be read based on the sampling coordinates of the target texture image using a Shader.

[0064] The mask texture array containing a plurality of array elements can be set in various ways, for example, a structure can be defined according to the color channels to be stored, which is used to store the mask map of each color channel in the target texture image. For example, when the color channels to be stored include R channel, G channel and B channel, the mask texture array containing a plurality of array elements can be set as follows:

[0065]

[0066] RGBArray can be the name of the structure, r, g, b can be elements in the structure, and tmask can be an instance of the structure, which can be used to obtain the mask texture array containing a plurality of array elements.

[0067] Then, the target texture image can be sampled based on the sampling coordinates corresponding to the target texture image, and the sampling color information corresponding to each color channel of the mask map can be obtained according to the sampling result. For example, the target texture image can be sampled as follows:

[0068]

[0069] Texture2dSampler can be a set sampler, UV can be the sampling coordinates corresponding to the target texture image, Texture can be the texture resource of the target texture image, and tmask can be the sampling result.

[0070] Then, the sampling color information of each color channel of the mask map can be written into an array element of the mask texture array, for example, the sampling color information of each color channel of the mask map can be written into an array element of the mask texture array as follows:

[0071]

[0072] In this way, the sampled color information color.r of the mask image in the R channel can be stored in the r element of the tmask mask texture array, the sampled color information color.g of the mask image in the G channel can be stored in the g element of the tmask mask texture array, and the sampled color information color.b of the mask image in the B channel can be stored in the b element of the tmask structure, so that the array element index corresponding to the r element is 0, the array element index corresponding to the g element is 1, the array element index corresponding to the b element is 2, and the like, and the mask texture array corresponding to the target texture image is obtained.

[0073] In an embodiment, the texture data corresponding to the target texture image can be loaded in a central processing unit (CPU) stage. Specifically, the texture data is stored in a corresponding disk directory, and then loaded from the disk to the memory, and from the memory to the video memory, so that the target texture image can be seen in the editor. Then, a rendering state can be called, and after the target texture image is read by using a Shader, the default rendering state of the Shader can be called in the editor, and then the default rendering state can be used to call a draw call to issue a draw instruction to the GPU. Thus, in the geometry stage of the GPU stage, there can be a preset geometry primitive in the game editor, and screen mapping is performed to correctly display the perspective relationship of the patch on the display. Then, in the rasterization stage, triangle traversal and perspective correction can be completed to calculate the color of the patch. In the per-patch operation stage, per-patch drawing can be performed to draw the target texture image in the viewport of the game editor.

[0074] In step 103, a target array element corresponding to a target array element index is determined in the mask texture array.

[0075] The target array element can be an array element in the mask texture array corresponding to the target array element index. For example, assuming that the target array element index is 1, the mask texture array includes three array elements [color.r, color.g, color.b], color.r represents the mask image of the target texture image in the R channel, color.g represents the mask image of the target texture image in the G channel, and color.b represents the mask image of the target texture image in the B channel, wherein the array element index corresponding to color.r is 0, the array element index corresponding to color.g is 1, and the array element index corresponding to color.b is 2, and then it can be determined that the target array element corresponding to the target array element index is color.g.

[0076] In step 104, a mask image corresponding to a target color channel of the target texture image is read from the target array element.

[0077] The target color channel can be a color channel corresponding to the target array element. For example, assuming that the mask texture array includes three array elements: [color.r, color.g, color.b], where color.r represents a mask image of the target texture image in the R channel, color.g represents a mask image of the target texture image in the G channel, and color.b represents a mask image of the target texture image in the B channel, and the target array element is color.g, the mask image of the target texture image in the G channel can be read through the target array element.

[0078] The target texture image in the target color channel can be read from the target array element in various ways. For example, the target texture image in the target color channel can be read from the target array element through a target shader. In this way, the user input mask image reading information can be stored in the target buffer, so that the target shader can obtain the mask image reading information stored in the target buffer based on the association between the target shader and the target buffer, determine the target array element index of the mask texture array based on the mask image reading information, determine the target array element corresponding to the target array element index in the mask texture array, and then read the mask image of the target texture image in the target color channel from the target array element.

[0079] In an embodiment, the implementation program code of the dynamic array index can be written in the Shader, and the parameters passed in can be filled in the parameters. The actual parameters, i.e., the mask reading parameters, passed into the Shader can be set by the game editor, and the final file can be packaged into the game package. When the game package reads this file, it will modify the actual rendering state in the Shader according to the parameters passed in, and display the accurate picture on the display according to the CPU-GPU rendering process.

[0080] In this way, the artist can call the corresponding Shader (i.e., the target shader) in the game engine editor, so that when setting the mask image of the target texture image for reading, the integer value in the value range of the mask reading parameter (parameter) can be input in the corresponding index box, so as to realize the reading of the mask image of the corresponding array element in the mask texture array of the target texture image, and realize the flexible reading of the mask image of each color channel of the target texture image.

[0081] In the existing mask image reading method, the point operator is generally used to read the mask texture, and a single fixed reading of a channel mask image is performed. The point operator can be used to access each component of a vector, for example, texture.r can be used to access the information of the red channel in the picture. Alternatively, the mask image is read in the form of a black and white image or an alpha image. However, if the point operator is used to read the mask image, an if statement is needed to control the selection of multiple channels, thereby increasing the Shader branch and reducing the rendering performance. The Shader branch refers to the branching in the Shader programming, which can cause thread divergence, that is, different threads select different execution paths, which breaks the parallelism of the GPU, and thus causes the rendering performance to decrease. If the mask image is directly read in the form of a black and white image or an alpha image, the required picture resource amount will be doubled. For games, the more picture resources required, the longer the download time of the players, and thus the game running efficiency will be reduced, and the game performance will be reduced. It can be seen that in the existing image processing method, the reading efficiency of the mask image is low.

[0082] Therefore, the embodiment of the present application provides an image processing method, which determines the target array element index corresponding to the mask texture array corresponding to the target texture image according to the mask image reading information, and reads the mask image of the target texture image on the target color channel in the mask texture array according to the target array element index. In this way, the three channels of the target texture image are flexibly called by using the dynamic index of the texture in the Shader, which can effectively reduce the picture resource amount of the mask image in the game resource. The related art personnel or developer only needs to select the integer parameter (0, 1, 2, etc.) corresponding to the array element index to flexibly call the mask image in each color channel of the target texture image, which greatly improves the reading flexibility of the mask image, and meets the needs of the art personnel or developer to flexibly call a mask image. In addition, each mask image is read by using the array method, which can avoid using the branch statement, and thus can avoid thread divergence caused by reading the mask image by using the point operator and the decrease of the rendering performance caused by the Shader branch, and effectively improves the reading efficiency of the mask image in the game.

[0083] From the above, the embodiment of the application reads the information of the mask image for the target texture image, the target texture image including the mask image on multiple color channels; determines the target array element index of the mask texture array according to the mask image reading information, wherein one array element in the mask texture array corresponds to the mask image of the target texture image on one color channel; determines the target array element corresponding to the target array element index in the mask texture array; and reads the mask image corresponding to the target color channel of the target texture image from the target array element.
