[0028] Figure 1 This is a flowchart illustrating a method for generating beauty effects according to an embodiment of this disclosure. The method can be executed by a beauty effects generation device, which can be implemented by software and / or hardware and can be configured in an electronic device, typically a mobile phone or tablet. The beauty effects generation method provided in this disclosure is applicable to scenarios involving the creation of special effects, and is particularly suitable for scenarios where new special effects are created based on existing ones. Figure 1 As shown, the method for generating beauty effects provided in this embodiment may include:

[0029] S101, Receive color adjustment operation for the first beauty effect.

[0030] The first makeup effect refers to a completed makeup effect, which can be either a released or unreleased effect. This first makeup effect can be a video effect, such as one applied to a video. Correspondingly, the color adjustment operation refers to adjusting the color of a specific makeup effect (i.e., the first makeup effect), such as selecting a color on the effect adjustment page of the first makeup effect. This color adjustment operation can be performed by the effect user or the effect creator. For example, while using a makeup effect (such as the first makeup effect), a user can adjust the color of the makeup effect by performing the color adjustment operation and use the adjusted new makeup effect to process the video; or, after completing the creation of a makeup effect (such as the first makeup effect), a user can further adjust the color of the makeup effect by performing the color adjustment operation to obtain a new makeup effect.

[0031] Specifically, when a user (such as a special effects user and / or special effects creator) wants to adjust the color of a first makeup effect, they can perform a color adjustment operation for that first makeup effect. For example, they can switch to the special effects adjustment page of the first makeup effect and select the color they want to use for the color adjustment. Correspondingly, the electronic device can receive the color adjustment operation performed by the user.

[0032] S102. In response to the color adjustment operation, determine the target color corresponding to the color adjustment operation, and adjust the color of the first beauty effect according to the target color to generate the second beauty effect.

[0033] The target color can be the color corresponding to the color adjustment operation, such as the color selected by the user through the color adjustment operation. The second makeup effect can be a new makeup effect created by the user based on the first makeup effect, such as a new makeup effect obtained by adjusting the color and / or position of the first makeup effect.

[0034] Specifically, when the electronic device receives a color adjustment command for the first makeup effect, it can determine the target color selected by the user and adjust the color of the first makeup effect accordingly. For example, it can determine the target color information that a corresponding pixel needs to be adjusted to based on the color information of the target color and the initial color information of each pixel in the first makeup effect, and then adjust the color of each pixel based on the target color information. Therefore, after the user completes the adjustment, they can instruct the electronic device to generate a second makeup effect by executing an effect generation operation, so as to publish the second makeup effect or use the second makeup effect for video processing.

[0035] In addition, when users adjust the first beauty effect, the electronic device can also display a real-time preview of the adjusted first beauty effect. For example, it can process the preset screen or the screen captured by the camera in real time using the adjusted first beauty effect and display the processed preview screen for users to view.

[0036] In this embodiment, users can adjust the completed makeup effects. For example, users can re-import the makeup effects into the effects creation tool for adjustments before or after the effects are released. This eliminates the need to repeatedly redraw the makeup effect materials and import them into the effects creation tool to view the effect before creating the effects. Compared to the previous approach where users had to redraw the makeup effect materials and import them into the effects creation tool to view the effect, and then re-import the redrawn effects into the effects creation tool if they were not satisfied with the effect, this approach simplifies the creation of makeup effects, improves the efficiency of effects creation, and enhances the user experience.

[0037] In one embodiment, adjusting the color of the first makeup effect based on the target color includes: determining a current adjustment coefficient corresponding to the current color component based on the target color for at least some color components of at least some pixels in the first makeup effect; and adjusting the color component value of the current color component using the current adjustment coefficient and the current transparency coefficient of the first makeup effect. Therefore, when adjusting the color, both the target color and the original color of the makeup effect can be comprehensively considered, improving the color adjustment effect of the makeup effect.

[0038] The current color component can be the color component whose color is currently being adjusted, i.e., the color component of the current pixel whose adjustment coefficient needs to be determined, such as the red, green, or blue color component of the current pixel. The current adjustment coefficient can be the adjustment coefficient of the current color component. The current transparency coefficient can be the transparency coefficient of the first makeup effect at the current moment. It can be the initial transparency coefficient of the first makeup effect, or it can be the transparency coefficient adjusted by the user, meaning that the user can adjust the transparency coefficient of the first makeup effect by performing a transparency coefficient adjustment operation.

[0039] For example, when adjusting the color of the first makeup effect, for at least some pixels in the first makeup effect, firstly, the adjustment coefficient corresponding to the corresponding color component is determined according to the target color and the color component value of the pixel in at least some color channels; then, the target color component value to which the corresponding color channel needs to be adjusted is determined according to the adjustment coefficient and the current transparency coefficient of the first makeup effect, and the color of the pixel is adjusted according to the target color component value.

[0040] Preferably, the color component value of each pixel in the first makeup effect can be adjusted. Here, assuming the initial color component values ​​of the pixel in each color channel before adjustment are (r0, g0, b0), and the current transparency coefficient of the first makeup effect is G0, the determined adjustment coefficients for each color component of the pixel are (c...). r c g c b If the target color component value that the pixel needs to be adjusted to in each color channel is (r0c), then the target color component value that the pixel needs to be adjusted to is (r0c). r G0, g0c g G0, b0c b G0).

[0041] In one implementation, the user can also adjust the addition position of the first beauty effect. Accordingly, when the first beauty effect is a portrait beauty effect, the method further includes: adjusting the addition position of the first beauty effect on the corresponding portrait part in response to the position adjustment operation of the first beauty effect.

[0042] Among them, portrait makeup effects can be understood as makeup effects added to the image of a person in the picture, such as makeup effects applied to the face or body. The following explanation uses the first makeup effect applied to the face as an example. Correspondingly, the portrait part can be the face or the body. The position adjustment operation can be the operation of adjusting the relative position of the first makeup effect and its corresponding portrait part, such as dragging the first makeup effect or scaling the position of the first makeup effect.

[0043] For example, when a user wants to adjust the placement of the first makeup effect, they can perform a position adjustment operation on the first makeup effect, such as dragging or adjusting the scaling factor. Upon receiving the user's position adjustment operation, the electronic device can determine the target position to which the first makeup effect needs to be adjusted, which will be the placement location for the first makeup effect. The device can then add the first makeup effect at that location, allowing the user to preview the adjusted effect.

[0044] In the above implementation, users can adjust the placement of the first makeup effect through a position adjustment operation. For example, if there is a deviation between the placement of the first makeup effect and the display position of its corresponding portrait part, the first makeup effect can be adjusted to align with the display position of its corresponding portrait part. Alternatively, if the placement of the first makeup effect is already aligned with the display position of its corresponding portrait part, the first makeup effect can be adjusted to be misaligned. This eliminates the need to repeatedly redraw the makeup effect material and import it into the effects creation tool to view the effect and create the makeup effect. Therefore, this not only simplifies the creation of makeup effects and improves the efficiency of makeup effect creation, but also meets the personalized needs of different users and enhances the user experience.

[0045] In one embodiment, adjusting the addition position of the first makeup effect on the corresponding portrait part includes: adjusting the key points corresponding to the first makeup effect on the corresponding portrait part; and determining the addition position of the first makeup effect based on the adjusted key points.

[0046] In this context, the key points corresponding to the first makeup effect in the corresponding portrait area can be understood as the key points for positioning the first makeup effect when adding it to that area. That is, the addition position of the first makeup effect can be determined based on these key points. Therefore, in this embodiment, the addition position of the first makeup effect in the corresponding portrait area can be adjusted by modifying the key points corresponding to it.

[0047] For example, the relative position of the first makeup effect and the corresponding part of the portrait can be adjusted according to the position adjustment operation. Based on the relative position, the key points corresponding to the adjusted first makeup effect in the corresponding part of the portrait are determined, and the addition position of the first makeup effect is determined based on the position of the key points. For example, when processing a video with the adjusted first makeup effect, the corresponding key points in the image of the person displayed in the video can be identified, and the first makeup effect can be added at the position corresponding to the key points. This allows for adjustment of the addition position of the makeup effect to meet the user's personalized needs.

[0048] This embodiment provides a method for generating beauty effects, which receives a color adjustment operation for a first beauty effect; in response to the color adjustment operation, determines the target color corresponding to the color adjustment operation, and adjusts the color of the first beauty effect according to the target color to generate a second beauty effect. This embodiment, by adopting the above technical solution, directly adjusts the first beauty effect to obtain the second beauty effect, without needing to redraw the beauty effect materials, thus simplifying the production difficulty of beauty effects, improving the production efficiency of beauty effects, and enhancing the user experience.

[0049] Figure 2 This is a flowchart illustrating another method for generating beauty effects according to an embodiment of this disclosure. The solution in this embodiment can be combined with one or more optional solutions in the above embodiments. Optionally, determining the current adjustment coefficient corresponding to the current color component based on the target color includes: determining a first sub-adjustment coefficient corresponding to the current color component and a second sub-adjustment coefficient corresponding to the current pixel based on the target color; and calculating the current adjustment coefficient corresponding to the current color component based on the first sub-adjustment coefficient and the second sub-adjustment coefficient.

[0050] Optionally, the position adjustment operation is a scaling factor adjustment operation. Adjusting the key points corresponding to the first makeup effect in the corresponding portrait part includes: scaling the three-dimensional model corresponding to the first makeup effect according to the target scaling factor corresponding to the scaling factor adjustment operation, so as to adjust the key points corresponding to the first makeup effect in the three-dimensional model, wherein the key points in the three-dimensional model correspond to the key points in the corresponding portrait part.

[0051] Correspondingly, such as Figure 2 As shown, the method for generating beauty effects provided in this embodiment may include:

[0052] S201, Receive color adjustment operation for the first beauty effect.

[0053] S202. In response to the color adjustment operation, determine the target color corresponding to the color adjustment operation, and determine the first sub-adjustment coefficient corresponding to the current color component and the second sub-adjustment coefficient corresponding to the current pixel based on the target color.

[0054] The first sub-adjustment coefficient can be the sub-adjustment coefficient corresponding to the current color component of the current pixel, and it can correspond only to the current color component. The second sub-adjustment coefficient can be the sub-adjustment coefficient corresponding to the current pixel, and it can correspond to each color component of the current pixel (i.e., the red color component, green color component, and blue color component of the current pixel). That is, each color component of the current pixel can share a second sub-adjustment coefficient.

[0055] For example, the first sub-adjustment coefficient corresponding to the current color component can be determined based on the color component value of the corresponding color component in the target color, and the second sub-adjustment coefficient corresponding to the current pixel can be calculated based on the gray value corresponding to the target color or the average / median value of each color component value of the target color.

[0056] In one embodiment, determining the first sub-adjustment coefficient corresponding to the current color component and the second sub-adjustment coefficient corresponding to the current pixel based on the target color includes: determining the first sub-adjustment coefficient corresponding to the current color component based on the color component value of the corresponding color component of the target color; and determining the second sub-adjustment coefficient corresponding to the current pixel based on the first grayscale value of the target pixel corresponding to the current pixel in the target grayscale image and the second grayscale value corresponding to the target color, wherein the pixel in the target grayscale image corresponds to the pixel in the first beauty effect.

[0057] The target grayscale image can be a grayscale image used for color adjustment of the first makeup effect. It can be set by the creator or user of the first makeup effect. The pixels in the target grayscale image correspond to the pixels in the first makeup effect, preferably in a one-to-one correspondence, to achieve pixel-by-pixel color adjustment of the first makeup effect. Correspondingly, the target pixel can be the pixel in the target grayscale image that corresponds to the current pixel in the first makeup effect. The first grayscale value can be the grayscale value of the target pixel. The second grayscale value can be the grayscale value corresponding to the target color, that is, the grayscale value obtained by grayscale conversion of the target color.

[0058] For example, when determining the first sub-adjustment coefficient, the color component values ​​of the corresponding color components of the target color can be normalized to obtain the first sub-adjustment coefficient of the current color component. For example, assuming that the color component values ​​of the target color in the red, green, and blue color channels are (r1, g1, b1), then when the current color component is the red color component, the first sub-adjustment coefficient corresponding to the current color component is r1 / 255; when the current color component is the green color component, the first sub-adjustment coefficient corresponding to the current color component is g1 / 255; and when the current color component is the blue color component, the first sub-adjustment coefficient corresponding to the current color component is b1 / 255.

[0059] When determining the second sub-adjustment coefficient, the first gray value and the second gray value can be normalized respectively, and their product can be used as the second sub-adjustment coefficient corresponding to the current pixel. For example, if the first gray value of the target pixel corresponding to the current pixel in the target grayscale image is G0 and the second gray value corresponding to the target color is G1, then the second sub-adjustment coefficient corresponding to the current pixel is (G0 / 255)×(G1 / 255).

[0060] In this embodiment, the colors of the makeup effects can be further adjusted pixel by pixel using grayscale images to achieve special effects such as local weakening, local enhancement, and / or shadows. This improves the efficiency of creating makeup effects, meets different user needs, enhances the visual effect of the makeup effects, and improves the user experience.

[0061] S203. Calculate the current adjustment coefficient corresponding to the current color component based on the first sub-adjustment coefficient and the second sub-adjustment coefficient.

[0062] For example, after obtaining the first sub-adjustment coefficient corresponding to the current color component of the current pixel and the second sub-adjustment coefficient corresponding to the current pixel, the product of the first sub-adjustment coefficient and the second sub-adjustment coefficient can be calculated as the current adjustment coefficient corresponding to the current color component of the current pixel.

[0063] It is understandable that when the first makeup effect does not have a corresponding target grayscale image, the color of the first makeup effect can be adjusted based solely on the first sub-adjustment coefficient. That is, the first sub-adjustment coefficient corresponding to the current color component of the current pixel can be directly used as the current adjustment coefficient of the current color component of the current pixel. When the first makeup effect has a corresponding target grayscale image, the second sub-adjustment coefficient corresponding to the current pixel can also be determined based solely on the target grayscale image. For example, the second sub-adjustment coefficient corresponding to the current pixel can be determined based on the grayscale value of the target pixel corresponding to the current pixel in the target grayscale image. This embodiment does not limit this.

[0064] S204. Adjust the color component value of the current color component using the current adjustment coefficient and the current transparency coefficient of the first beauty effect.

[0065] For example, suppose the initial color component values ​​of the current pixel in the red, green, and blue color channels before adjustment are (r0, g0, b0), the grayscale value of the pixel corresponding to the current pixel in the target grayscale image is G0, the color component values ​​of the target color in each color channel are (r1, g1, b1), the grayscale value corresponding to the target color is G1, the current transparency coefficient of the first makeup effect is c0, and suppose the adjustment coefficients corresponding to each color component of the current pixel are (c r c g c b If the target color component value that the current pixel needs to be adjusted to in each color channel is (r2, g2, b2), then:

[0066] c r =(r1 / 255)×(G0 / 255)×(G1 / 255);

[0067] c g =(g1 / 255)×(G0 / 255)×(G1 / 255);

[0068] c b =(b1 / 255)×(G0 / 255)×(G1 / 255);

[0069] The target color component values ​​that the current pixel needs to be adjusted to in each color channel are as follows:

[0070] r2=r0c r G0=r0×(r1 / 255)×(G0 / 255)×(G1 / 255)×G0;

[0071] g2=g0c g G0=g0×(g1 / 255)×(G0 / 255)×(G1 / 255)×G0;

[0072] b2=b0c b G0=b0×(b1 / 255)×(G0 / 255)×(G1 / 255)×G0.

[0073] S205. In response to the scaling factor adjustment operation for the first makeup effect, the three-dimensional model corresponding to the first makeup effect is scaled according to the target scaling factor corresponding to the scaling factor adjustment operation, so as to adjust the key points corresponding to the first makeup effect in the three-dimensional model, wherein the key points in the three-dimensional model correspond to the key points in the corresponding human portrait parts.

[0074] The 3D model corresponding to the first makeup effect can be the model used for texture rendering of the first makeup effect. It can be obtained by using a preset keypoint recognition algorithm to identify keypoints, and then using the identified keypoints as mesh vertices for mesh division. This keypoint recognition algorithm can be the same as the keypoint recognition algorithm used for the corresponding human body parts, and can also be the same keypoint recognition algorithm used by the creator of the first makeup effect when identifying keypoints on the base model image when drawing the effect materials. The keypoints in the 3D model can be the mesh vertices of the 3D model. The scaling factor adjustment operation is the operation to adjust the scaling factor of the first makeup effect. Correspondingly, the target scaling factor is the scaling factor adjusted to by this scaling factor adjustment operation.

[0075] In this embodiment, the key points corresponding to the first makeup effect in the 3D model can be adjusted by scaling the 3D model corresponding to the first makeup effect, thereby adjusting the key points corresponding to the first makeup effect in the corresponding portrait part. That is, the mesh covered by the first makeup effect in the 3D model can be adjusted by scaling the 3D model, thereby adjusting the addition position of the first makeup effect in the corresponding portrait part.

[0076] For example, a preset point (such as the center of the 3D model or a point on the boundary of the 3D model) can be used as the origin, and the 3D model can be scaled according to the target scaling factor adjusted by the scaling factor adjustment operation. For example, for each mesh vertex in the 3D model, assuming the coordinates of the mesh vertex are (v x v y ), the origin coordinates are (v x0 v y0 The target scaling factor is (s) x s y If ), then the coordinates of the grid vertex after scaling are ([(v x -v x0 )×s x ]+v x0 ,[(v y -v y0 )×s y ]+v y0 ).

[0077] S206. Determine the addition position of the first beauty effect according to the adjusted correspondence to generate the second beauty effect.

[0078] It should be noted that the above-described order of response to color adjustment and scaling factor adjustment operations is merely an illustrative example and does not restrict the execution order of each step. For example, the user may perform the scaling factor adjustment operation first and then the color adjustment operation, or perform multiple color adjustment operations and multiple scaling factor adjustment operations in a cross-cutting manner. In this case, the electronic device can respond to each trigger operation according to the order of the user's execution, thereby ultimately obtaining the second beauty effect.

[0079] The method for generating beauty effects provided in this embodiment adjusts the color of the first beauty effect according to the first sub-adjustment coefficient and the second sub-adjustment coefficient, and adjusts the addition position of the first beauty effect by scaling the corresponding three-dimensional model. This not only improves the creation efficiency of beauty effects, but also meets different user needs and enhances the user experience.

[0080] Figure 3 This is a structural block diagram of a makeup effect generation device provided in an embodiment of this disclosure. The device can be implemented by software and / or hardware, and can be configured in an electronic device, typically a mobile phone or tablet computer. It can create new effects based on existing effects by executing a makeup effect generation method.

[0082] Color adjustment module 302 is used to respond to the color adjustment operation, determine the target color corresponding to the color adjustment operation, and adjust the color of the first beauty effect according to the target color to generate the second beauty effect.

[0083] This embodiment provides a device for generating beauty effects. It receives a color adjustment operation for a first beauty effect via an operation receiving module; the color adjustment module responds to the color adjustment operation, determines the target color corresponding to the operation, and adjusts the first beauty effect according to the target color to generate a second beauty effect. This embodiment, by employing the above technical solution, directly adjusts the first beauty effect to obtain the second beauty effect, eliminating the need to redraw the beauty effect materials. This simplifies the production difficulty of beauty effects, improves production efficiency, and enhances the user experience.

[0084] In the above scheme, the color adjustment module 302 may include: a coefficient determination unit, used to determine the current adjustment coefficient corresponding to the current color component based on the target color for at least some color components of at least some pixels in the first beauty effect; and a color adjustment unit, used to adjust the color component value of the current color component using the current adjustment coefficient and the current transparency coefficient of the first beauty effect.

[0086] In the above scheme, the first coefficient determining subunit can be used to: determine the first sub-adjustment coefficient corresponding to the current color component based on the color component value of the corresponding color component of the target color; and determine the second sub-adjustment coefficient corresponding to the current pixel based on the first gray value of the target pixel corresponding to the current pixel in the target grayscale image and the second gray value corresponding to the target color, wherein the pixel in the target grayscale image corresponds to the pixel in the first beauty effect.

[0087] In the above scheme, the first beauty effect can be a portrait beauty effect. The beauty effect generation device provided in this embodiment may further include: a position adjustment module, used to adjust the addition position of the first beauty effect on the corresponding portrait part in response to the position adjustment operation of the first beauty effect.
