[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0032] In response to the technical problem mentioned above that the existing head decoration methods have poor decoration effects and cannot meet the actual needs of users, the present disclosure provides an image processing method, device, equipment, computer-readable storage medium and product.

[0033] It should be noted that the image processing methods, devices, equipment, computer-readable storage media and products provided by the present disclosure can be used in various scenarios requiring head decoration.

[0034] Existing head decoration methods generally involve directly placing the headdress effect at the corresponding position on the 3D head model without changing the original face occlusion relationship. However, this method cannot achieve the headdress effect of partially obscuring the face regardless of the size and shape of the head, and it cannot use glass materials in the obscured area.

[0035] In solving the above technical problems, the inventors discovered through research that, in order to achieve a decorative effect that obscures a portion of a person's face and utilize glass materials in areas where the face is obscured, after receiving a head decoration request, a head mask filled with a background color matching the target head decoration coverage area selected by the user can be generated. Specifically, the background color-filled head mask can be a head mask filled with the background color. The target head decoration selected by the user is preprocessed and then fused with the background color-filled head mask to obtain the head decoration result.

[0036] Figure 1 This is a schematic diagram of the system architecture based on which the present disclosure is based. Figure 1 As shown, the system architecture based on which the present disclosure is based includes at least: a terminal device 11 and a server 12, wherein the server 12 is provided with an image processing device, which can be written in languages ​​such as C / C++, Java, Shell or Python; the terminal device 11 can be, for example, a desktop computer, a tablet computer, etc.

[0037] Based on the above system architecture, the image processing device in the server 12 can obtain the head decoration request sent by the terminal device 11, and generate a head decoration result 15 based on the head decoration request, so as to display the background on the part of the face blocked by the target head decoration when the target head decoration 13 matches the user's head 14.

[0038] Figure 2 A flow chart of the image processing method provided by the embodiment of the present disclosure is shown as follows: Figure 2 As shown, the method includes:

[0039] Step 201: Obtain a head decoration request, wherein the head decoration request includes an image to be processed and a target head decoration, and the target head decoration is used to decorate a part of the head area.

[0040] The execution subject of this embodiment is an image processing device, which can be coupled to a server. The server is capable of communicating with a terminal device, thereby obtaining head decoration requests initiated by a user through a triggering operation on the terminal device. Optionally, the image processing device can also be coupled to the terminal device, thereby performing head decoration operations in response to the head decoration requests triggered by the user on the terminal device.

[0041] The image processing method provided by this embodiment can be applied to the application scenario of online fitting, for example, it can simulate the decorative effect of the user's actual wear according to the headwear such as hats selected by the user. Alternatively, the image processing method provided by this embodiment can be applied to the application scenario of image processing, for example, it can add the headwear selected by the user to the user's head area according to the special effects, stickers and other headwear selected by the user. Alternatively, the image processing method provided by this embodiment can be applied to the decoration scenario of digital accessories. Among them, the digital accessories can be of different materials, for example, they can be made of transparent glass, or they can be made of opaque materials, etc. For example, when the target head decoration selected by the user is made of glass, the image processing method provided by this embodiment can be used to achieve the display effect of displaying the background on the part of the face blocked by the target head decoration when the target head decoration matches the user's head. The present disclosure does not limit the application scenario.

[0042] In this embodiment, a user can browse and select head decorations on a terminal device. Once the user's selected target head decoration is obtained, an image to be processed that includes at least the user's head can be obtained, where the target head decoration is used to decorate a portion of the head area. Specifically, the image to be processed can be captured in real time by an image capture device preset in the terminal device, or a pre-stored image to be processed can be selected from a preset storage path based on the user's selection, although this disclosure does not impose any restrictions on this.

[0043] Accordingly, after obtaining the target head device selected by the user and the image to be processed, the terminal device can initiate a head decoration request. Accordingly, the image processing device can obtain the head decoration request.

[0044] Step 202: Perform image processing on the image to be processed according to the head decoration request to obtain a head mask filled with a background color that matches the target head decoration coverage area.

[0045] In this embodiment, in order to optimize the decoration effect of the target head decoration, after the head decoration request is obtained, an image processing operation may be performed on the image to be processed according to the head decoration request.

[0046] Optionally, a segmentation operation can be performed on the head mask that matches the target head decoration in the processed image. The head segmentation operation can be implemented using a head segmentation algorithm, or any other method can be used to implement the head segmentation operation, which is not limited by the present disclosure.

[0047] Optionally, the pixel value corresponding to the head area in the head mask is 1, and the pixel values ​​corresponding to other areas are 0, so that the display effect of the target head decoration can be optimized based on the head mask.

[0048] Furthermore, the target head decoration can be made of a transparent material, such as glass, or an opaque material. To further optimize the display effect, the background can be displayed through the transparent material within the area covered by the target head decoration. Therefore, after obtaining a head mask that matches the target head decoration, the head mask can be blurred to obtain a head mask filled with the background color that matches the area covered by the target head decoration.

[0049] Step 203: Generate a three-dimensional head model corresponding to the image to be processed, and fuse the three-dimensional head model corresponding to the image to be processed with the target head decoration to obtain a target three-dimensional model.

[0050] In this embodiment, the target head ornament can also be processed accordingly based on the head ornament request. The target head ornament can be a three-dimensional ornament model. Therefore, based on the image to be processed in the head ornament request, a three-dimensional head mold corresponding to the head region in the image to be processed can be generated. The three-dimensional head mold corresponding to the image to be processed is then fused with the target head ornament to obtain the target three-dimensional model.

[0051] Step 204: performing a fusion operation on the target three-dimensional model and the background color-filled head mask to obtain a head decoration result.

[0052] In this embodiment, after obtaining the target 3D model and the background color-filled head mask, a fusion operation can be performed on the target 3D model and the background color-filled head mask to obtain the head decoration result. Because the pixel values ​​corresponding to the head area in the background color-filled head mask are 1, and the pixel values ​​corresponding to other areas are 0, by fusing the target 3D model with the background color-filled head mask, the target head decoration can be more accurately displayed within the area covered by the target head decoration, while the user's head can be displayed in other areas. For example, the target head decoration can be a headdress that covers the upper half of the face. After completing the above image processing, the target head decoration can be displayed on the upper half of the head, while the user's face can be displayed on the upper half of the head.

[0053] Figure 3 A schematic diagram of a head decoration provided in an embodiment of the present disclosure is shown in FIG. Figure 3 As shown, a user-selected target head decoration 31 and an image to be processed are obtained. A head region 32 in the image to be processed is segmented, and a head decoration result 33 is obtained by performing image processing on the target head decoration 31 and the head region 32. This head decoration result 33 can achieve a decorative effect by obscuring a portion of a person's face.

[0054] Furthermore, based on any of the above embodiments, generating a three-dimensional head model corresponding to the image to be processed includes:

[0055] The texture of the head area in the image to be processed is mapped onto a preset three-dimensional head model to obtain the three-dimensional head model corresponding to the image to be processed.

[0056] In this embodiment, a texture mapping method may be used to implement the generation operation of the three-dimensional head model corresponding to the image to be processed.

[0057] Specifically, the texture of the head area in the image to be processed may be mapped onto a preset three-dimensional head model to obtain a three-dimensional head model corresponding to the image to be processed.

[0058] The image processing method provided in this embodiment generates a background color-filled head mask that matches the target head decoration coverage area selected by the user after obtaining a head decoration request, generates a three-dimensional head model corresponding to the image to be processed, and fuses the three-dimensional head model corresponding to the image to be processed with the target head decoration to obtain a target three-dimensional model. After the target three-dimensional model is fused with the background color-filled head mask, the background can be displayed on the part of the face obscured by the target head decoration when the target head decoration matches the user's head, thereby optimizing the display effect of the head decoration and improving the user experience.

[0059] Figure 4A flowchart of an image processing method provided by another embodiment of the present disclosure is provided. Based on any of the above embodiments, Figure 4 As shown, step 202 includes:

[0060] Step 401: Segment the head region in the image to be processed using a preset head segmentation algorithm to obtain a head mask to be processed.

[0061] Step 402: Determine the coverage area corresponding to the target head decoration, and segment the head mask to be processed according to the coverage area to obtain a target head mask that matches the coverage area.

[0062] Step 403: Fill the target head mask with the background color corresponding to the image to be processed using a preset fuzzy algorithm to obtain the background color-filled head mask.

[0063] In this embodiment, in order to optimize the decoration effect of the target head decoration, after obtaining the head decoration request, an image processing operation may be performed on the image to be processed according to the head decoration request to obtain a head mask filled with a background color.

[0064] First, a head segmentation algorithm can be used to segment the head region in the image to be processed to obtain a head mask to be processed. The head segmentation algorithm can accurately segment the head, hair, and other contents.

[0065] Furthermore, since the target head decoration can be a decoration that covers part of the head area, different head decorations cover different areas. Therefore, in order to make the target head decoration fit the user's head area more closely and further enhance the decorative effect of the target head decoration, after obtaining the head mask to be processed, the corresponding coverage area of ​​the target head decoration can be determined. For example, the coverage area of ​​the target head decoration can be the upper half of the face, the lower half of the face, the hair part, the left face, the right face, etc. Therefore, after determining the corresponding coverage area of ​​the target head decoration, the head mask to be processed can be segmented according to the coverage area to obtain a target head mask that matches the coverage area. For example, when the coverage area of ​​the target head decoration is the upper half of the face, the head mask to be processed can be segmented to obtain a target head mask that only includes the upper half of the face.

[0066] Furthermore, the target head decoration can be made of a transparent material, such as glass, or an opaque material. To accommodate different decorative materials, after obtaining a head mask to be processed that matches the coverage area, a preset fuzzy algorithm can be used to process the target head mask to obtain a background color-filled head mask. Specifically, an image inpainting algorithm can be used to fill the target head mask with the background color corresponding to the image to be processed to obtain a background color-filled head mask.

[0067] The image processing method provided in this embodiment, after receiving a head decoration request, segments the head region in the image to be processed to obtain a head mask to be processed. By segmenting the head mask to be processed based on the coverage area corresponding to the target head decoration, the target head mask is obtained. This ensures that the coverage area of ​​the target head mask is more closely aligned with the target head decoration, thereby enhancing the decorative effect of the target head decoration during subsequent fusion. Furthermore, by filling the target head mask with the background color corresponding to the image to be processed, the background effect can be displayed through the glass when the target head decoration is made of glass, thereby optimizing the display effect of the target head decoration.

[0068] Further, based on any of the above embodiments, step 402 includes:

[0069] Determine coordinate information in the head mask to be processed that matches an edge position of the coverage area.

[0070] According to the coordinate information, a hiding operation is performed on the area of ​​the head mask to be processed that does not match the coverage area to obtain the target head mask.

[0071] In this embodiment, in order to obtain the head mask to be processed that matches the coverage area, a segmentation operation of the head mask to be processed may be implemented specifically through coordinates.

[0072] Specifically, coordinate information matching the edge position of the coverage area in the head mask to be processed can be determined. Based on the coordinate information, the area of ​​the head mask to be processed that does not match the coverage area is hidden to obtain the head mask to be processed that matches the coverage area.

[0073] Figure 5 A schematic diagram of mask processing provided in an embodiment of the present disclosure is shown in FIG. Figure 5 As shown, after the head area in the image to be processed is segmented to obtain the head mask 51 to be processed, if the coverage area corresponding to the target head decoration is the upper half of the face, the lower half of the face to be processed mask 51 can be hidden to obtain the head mask 52 to be processed that matches the coverage area.

[0074] like Figure 5 As shown, the coordinate value of the upper left corner of the head mask 51 to be processed can be (0,0) of uv, and the coordinate value of the lower right corner can be (1,1) of uv. Therefore, based on the above coordinate values, in order to achieve the segmentation operation of the head mask to be processed corresponding to the upper half of the face, the area with a uv value < 0.5 can be filtered and hidden to obtain a head mask to be processed that matches the covered area.

[0075] The image processing method provided in this embodiment partially hides the head mask to be processed based on coordinate information that matches the edge position of the coverage area, thereby accurately retaining the head mask to be processed that matches the coverage area, so that the coverage area of ​​the head mask to be processed is more closely aligned with the target head decoration, and thus in the subsequent fusion process, the decorative effect of the target head decoration can be improved.

[0076] Further, based on any of the above embodiments, step 403 includes:

[0077] A preset fuzzy algorithm is used to fill the human body area in the image to be processed with the background color corresponding to the image to be processed to obtain a fuzzy human body image.

[0078] A fusion operation is performed on the blurred human body image and the target head mask to obtain the background color-filled head mask.

[0079] In this embodiment, to obtain a head mask filled with the background color, a preset fuzzy algorithm is first used to fill the human body region in the image to be processed with the background color corresponding to the image to be processed, thereby achieving scene color transfer and obtaining a blurred human body image. A fusion operation is then performed on the blurred human body image and the head mask to be processed that matches the covered area. The intersection of the blurred human body image and the head mask to be processed that matches the covered area is taken to obtain a head mask filled with the background color. Specifically, the preset fuzzy algorithm can be an image inpainting algorithm that transfers scene color based on the human body segmentation mask, using the scene color to fill the human body.

[0080] Optionally, after obtaining the head mask to be processed that matches the coverage area, a preset fuzzy algorithm may be directly used to perform fuzzy processing on the head mask to be processed that matches the coverage area to obtain a head mask filled with the background color.

[0081] The image processing method provided in this embodiment obtains a blurred human body image by filling the human body area in the image to be processed with the background color corresponding to the image to be processed, and then fuses the blurred human body image and the head mask to be processed that matches the covered area, thereby obtaining a head mask filled with the background color that matches the covered area. When the target head decoration is made of glass, the background effect can be displayed through the glass, thereby optimizing the display effect of the target head decoration.

[0082] Furthermore, based on any of the above embodiments, after step 401, the following steps may be further included:

[0083] Performing a dilation operation on the area corresponding to the head mask to be processed.

[0084] In this embodiment, due to possible errors in the image processing process, the generated head mask to be processed may have some incomplete edge processing. For example, some hair pixels may remain in the hair details and are not included in the output result. As a result, when the head mask to be processed is directly used for subsequent image processing, the hair edges may have jagged residues.

[0085] Therefore, in order to further improve the decorative effect of the target head decoration, a dilation operation may be performed on the area corresponding to the head mask to be processed.

[0086] The image processing method provided in this embodiment performs a dilation operation on the area corresponding to the head mask to be processed, thereby ensuring the integrity of the edge area, avoiding insufficient detail processing, and further improving the effect of head decoration.

[0087] Furthermore, based on any of the above embodiments, the dilation operation on the area corresponding to the head mask to be processed includes:

[0088] A preset rectangular template is used to perform a traversal operation on each pixel in the image to be processed, wherein the pixel value of the area corresponding to the mask of the head to be processed in the image to be processed is greater than the pixel value of the area corresponding to the mask of the non-head to be processed.

[0089] During the traversal process, it is determined whether the pixel value of the central area of ​​the rectangular template is greater than the pixel value of the surrounding area.

[0090] If so, the pixel values ​​of the area covered by the rectangular template are adjusted to be the same as the pixel values ​​of the area corresponding to the head mask to be processed.

[0091] Checking whether the traversal operation for each pixel in the image to be processed has been completed. If not, returning to the step of traversing each pixel in the image to be processed using the preset rectangular template until the traversal operation for each pixel in the image to be processed is completed. If so, determining that the dilation operation for the head mask to be processed has been completed.

[0092] In this embodiment, a rectangular template may be preset, for example, a 3*3 rectangular template, and the rectangular template is used to implement the dilation operation on the area corresponding to the head mask to be processed.

[0093] Specifically, the pixel value of the area corresponding to the head mask to be processed in the image to be processed is greater than the pixel value of the area corresponding to the non-head mask to be processed. For example, the pixel value of the area corresponding to the head mask to be processed is 1, while the pixel values ​​of other areas are 0.

[0094] A preset rectangular template can be used to traverse each pixel in the image to be processed. During the traversal process, the pixel value at the center of the rectangular template is checked to see if it is greater than the pixel values ​​in the surrounding area. If so, the center of the rectangular template is covered by the mask for the head to be processed, while the remaining area is not. Therefore, the pixel values ​​of the area covered by the rectangular template can be adjusted to match the pixel values ​​of the area corresponding to the mask for the head to be processed.

[0095] A check is performed to determine whether the traversal operation for each pixel in the image to be processed has been completed. If so, the dilation operation for the head mask to be processed has been completed. Otherwise, the dilation operation for the head mask to be processed has not yet been completed. The process can return to the step of traversing each pixel in the image to be processed using a preset rectangular template until the traversal operation for each pixel in the image to be processed is completed, thereby achieving the dilation operation for the head mask to be processed.

[0096] Figure 6 A schematic diagram of mask expansion provided by an embodiment of the present disclosure, such as Figure 6 As shown, a preset 3*3 rectangular template 61 can be used to traverse an image 62 to be processed, which includes a head mask 63 to be processed. During the traversal process, the head mask is expanded by comparing the central pixel value of rectangular template 61 with the surrounding pixel values, obtaining a final expansion result 64.

[0097] The image processing method provided in this embodiment uses a preset rectangular template to traverse the image to be processed, and expands the mask area based on the comparison between the central pixel of the rectangular template and the surrounding pixels, thereby being able to quickly implement the expansion operation of the head mask to be processed, thereby avoiding the technical problem of poor edge detail processing.

[0098] Furthermore, based on any of the above embodiments, before step 204, the following steps may be further included:

[0099] Rendering operations are performed on the three-dimensional head model and the target head decoration corresponding to the image to be processed respectively according to a preset rendering order.

[0100] The preset rendering order is to render the target head decoration first, and then render the three-dimensional head model corresponding to the image to be processed after the target head decoration is rendered.

[0101] In this embodiment, the target head decorations vary widely. For example, a glass head decoration may also include decorative elements such as flowers. Therefore, to fully display the target head decorations without being obscured by details of the user's face, a pre-set rendering order can be used. The pre-set rendering order prioritizes rendering the target head decorations, followed by rendering the 3D head model corresponding to the image to be processed.

[0102] Since the 3D head model corresponding to the image to be processed is a model with a human face texture mapped onto it, rendering the target head decoration first and then the 3D head model corresponding to the image to be processed allows the facial features in the areas not covered by the target head decoration to be correctly displayed based on depth contrast without obscuring the decorative details in the target head decoration. Therefore, to further optimize the decorative effect of the target head decoration, the 3D head model corresponding to the image to be processed and the target head decoration can be rendered separately according to a preset rendering order.

[0103] The image processing method provided in this embodiment prioritizes rendering of the target head decoration. After the target head decoration is rendered, the 3D head model corresponding to the image to be processed is rendered. This method can achieve the correct occlusion relationship between the target head decoration and the human face, avoid occlusion of the target head decoration by the human face, and further optimize the decoration effect.

[0104] Furthermore, based on any of the above embodiments, after step 204, the following steps may be further included:

[0105] The ear region in the image to be processed is segmented using a preset ear segmentation algorithm.

[0106] Accordingly, step 204 includes:

[0107] A fusion operation is performed on the target three-dimensional model, the background color-filled head mask, and the ear region to obtain the head decoration result.

[0108] In this embodiment, some target head decorations require the user's ears to be visible, but the 3D head model corresponding to the processed image does not include ears. Therefore, to better match the decorative effect of the target head decoration, a preset ear segmentation algorithm can be used to segment the ear region in the processed image. A fusion operation is performed on the target 3D model, the background color-filled head mask, and the ear region to obtain the head decoration result.

[0109] The image processing method provided in this embodiment segments the ear region in the image to be processed through a preset ear segmentation algorithm, and adds the ear region to the final decoration result, thereby ensuring the integrity of the head.

[0110] Figure 7 A schematic diagram of the structure of an image processing device provided in an embodiment of the present disclosure is shown in FIG. Figure 7 As shown, the device includes: an acquisition module 71, a processing module 72, a generation module 73, and a fusion module 74. The acquisition module 71 is used to obtain a head decoration request, wherein the head decoration request includes an image to be processed and a target head decoration, and the target head decoration is used to decorate a part of the head area. The processing module 72 is used to perform image processing operations on the image to be processed according to the head decoration request to obtain a background color-filled head mask that matches the area covered by the target head decoration. The generation module 73 is used to generate a three-dimensional head model corresponding to the image to be processed, and fuse the three-dimensional head model corresponding to the image to be processed with the target head decoration to obtain a target three-dimensional model.
