The wearable device may be a smart watch, a smart bracelet, a watch phone, a smart foot ring, a smart earring, a smart necklace, a smart headset, or the like, and the embodiment of the present invention is not limited.

The following takes a terminal device as an example to exemplarily describe the method for changing the simulated facial image provided by the embodiment of the present invention.

The method for simulating the change of the facial image provided by the embodiment of the invention can be applied to scenes in which the user expression changes in the process of simulating the facial features of the user by the terminal equipment.

Example one

As shown in fig. 1, an embodiment of the present invention provides a method for simulating a change in facial image, which may include the steps of:

101. a first user facial image is acquired.

In the embodiment of the invention, the terminal equipment can acquire the first user face image through the camera.

Optionally, the acquiring, by the terminal device, the first user face image may specifically include: continuously acquiring a plurality of frames of user face images; comparing the face images of multiple frames of users to obtain a comparison result; and when the resident abnormal display area exists in the multi-frame user face images according to the comparison result, repairing the resident abnormal display area according to the normal display area of each frame of user face images.

The resident abnormal display area is the same abnormal display area with the frequency higher than the frequency threshold value in the face images of the multiple frames of users.

It should be noted that, for an abnormal display area caused by dirt/cracks on a camera or an abnormal display area caused by dirt/cracks on a screen area corresponding to a camera under a screen, a difference between pixel values of the abnormal display area and adjacent areas of the abnormal display area is generally large, so that a terminal device may identify an edge of each image area in a user face image through an edge identification algorithm, after determining the edge of the image area, may compare the pixel value of the edge of the image area with the pixel value of an adjacent pixel point outside the edge of the image area, and if the difference between the pixel value of the edge and the pixel value of the adjacent pixel point is greater than a preset threshold, determine that the image area in the edge is the abnormal display area.

Further, after determining that the resident abnormal display area exists in the face images of the plurality of frames of users according to the comparison result, the terminal device may further: determining the size of an inscribed circle of the resident abnormal display area and the size of an circumscribed circle of the resident abnormal display area; calculating a first ratio of the size of the inscribed circle to the size of the circumscribed circle; if the first ratio is smaller than the first ratio threshold, determining that the resident abnormal display area is caused by damage of the camera, or caused by damage of a screen area corresponding to the camera; and if the first ratio is larger than or equal to the first ratio threshold, determining that the resident abnormal display area is caused by the dirt of the camera or the dirt of the screen area corresponding to the camera.

It should be noted that, because the resident abnormal display area caused by general dirt is close to a circle, the difference between the sizes of the inscribed circle and the circumscribed circle of the resident abnormal display area is small, the resident display area caused by damage to the camera or the screen area corresponding to the camera is close to a linear shape, and the difference between the sizes of the inscribed circle and the circumscribed circle of the resident abnormal display area is large. The size of the circle involved in the embodiment of the present invention may be the area, radius or diameter of the circle.

In this optional implementation manner, the terminal device may detect whether an abnormal display area exists in the currently acquired user face image, and if so, repair the abnormal display area, so that the terminal device may acquire a normal user face image, and the terminal device may determine a reason for causing abnormal display according to size information of the abnormal display area, which is more favorable for the terminal device to repair.

102. And determining M first user image areas where preset M face feature points are located.

In the embodiment of the present invention, the terminal device may determine, from the first user face image, M first user image regions where M preset face feature points are located.

The M facial feature points may be points which are stored in advance by the terminal device and can represent facial features of the user, as shown in fig. 2, which is a schematic diagram of a facial image of the user, and the M facial feature points may be facial feature points shown in 201 to 216 in fig. 2.

It should be noted that M facial feature points are used to indicate facial features of the user (e.g., corners of the mouth, corners of the eyes, and eyebrows) in the first user facial image, and are not specific pixel points in the first user facial image, and M is an integer greater than or equal to 1.

It should be noted that M facial feature points correspond to M first user image regions, where each facial feature point may correspond to one first user image region, and the first user image region is formed by specific pixel points in the first user facial image.

Illustratively, as the point 212 and the point 214 in fig. 2 are used to indicate the right mouth corner and the left mouth corner of the user, respectively, and the left mouth corner and the right mouth corner may be raised when the user smiles, at this time, the point 212 and the point 214 are still used to indicate the right mouth corner and the left mouth corner of the user, respectively, but the first user image areas corresponding to the point 212 and the point 214 are changed.

Optionally, in the first user face image, each face feature point may correspond to one first user image region, and the number of pixel points in each first user image region may be one or multiple.

Optionally, the terminal device may determine, through a face recognition algorithm, M first user image regions where M preset face feature points are located.

Optionally, the face recognition algorithm may be an insight face (also written as insight face) algorithm, the insight face algorithm is mainly to acquire a face recognition function by acquiring a plurality of face data for training, and in the embodiment of the present invention, after the terminal device acquires the first user face image, the insight face algorithm may rapidly and accurately mark M face feature points on the first user face image through the face recognition function, so as to determine M first user image regions.

Optionally, the face recognition algorithm may also be a FaceNet (also written as FaceNet) algorithm, where the FaceNet algorithm mainly performs face recognition from an image to a european space through end-to-end learning, and based on this code, in this embodiment of the present invention, after a terminal device acquires a first user face image, the FaceNet algorithm may mark M face feature points on the first user face image quickly and accurately through the code, so as to determine M first user image regions.

103. A first simulated facial avatar is displayed.

In an embodiment of the present invention, the terminal device may display the first simulated face figure based on the first user face image.

It should be noted that, the terminal device determines the first simulated image region in the target face image according to the position information of each target image region of the first user face image, and adjusts the pixel value of the first simulated image region according to the pixel value of the preset image region corresponding to the target face feature point in the target face image, so as to obtain the first simulated face image. Wherein the target face image is an image pre-stored in advance by the terminal device.

For example, as shown in fig. 4, which is a schematic diagram of a simulated face image, points 201 to 216 in fig. 4 may be facial feature points, which are the same as points 201 to 216 in fig. 2, and when the user smiles and raises the right mouth corner, points 212 in fig. 2 move upward. If the terminal device is in a mirror image display, point 212 in fig. 4 is also moved upward; if the terminal device is a corresponding display, point 214 in FIG. 4 is also moved upward.

104. A second user facial image is acquired.

In the embodiment of the invention, the terminal equipment can acquire the second user face image through the camera.

105. And determining M second user image areas where the M face feature points are located.

In the embodiment of the present invention, the terminal device may determine, from the second user face image, M second user image regions where M preset face feature points are located.

It should be noted that the M facial feature points are not specific pixel points in the second user facial image, and M is an integer greater than or equal to 1. The M second user image regions are each in a second user face image.

Optionally, in the second user face image, each face feature point may correspond to one second user image region, and the number of pixel points in each second user image region may be one or multiple, which is not limited in the embodiment of the present invention.

106. And determining the position variation of the first target user image area and the second target user image area.

In the embodiment of the present invention, the terminal device may determine the amount of change in the positions of the first target user image area and the second target user image area with respect to the target facial feature point.

The target facial feature point is any one of the M facial feature points; the first target user image area and the second target user image area correspond to the target facial feature points respectively; the first target user image area is positioned in the first user face image, and the first target user image area is any one of the M first user image areas; the second target user image area is in the second user face image, and the second target user image area is any one of the M second user image areas.

For example, as shown in fig. 3, another schematic diagram of a user face image is shown, and assuming that the terminal device uses point 212 in fig. 2 as a target facial feature point, point 217 in fig. 2 may be a first target user image area, and point 317 in fig. 3 may be a second target user image area. The terminal device can acquire the amount of change in position of 217 and 317.

Optionally, determining the position variation of the first target user image area and the second target user image area may specifically include two optional implementation manners:

a first alternative implementation: acquiring a first target coordinate value, wherein the first target coordinate value is an average value of coordinate values of each pixel point in a first target user image area; acquiring a second target coordinate value, wherein the second target coordinate value is an average value of coordinate values of each facial feature point in a second target user image area; and obtaining the position variation according to the first target coordinate value and the second target coordinate value.

The terminal device can establish a first coordinate system for the first user face image and a second coordinate system for the second user face image, the coordinate origins of the first coordinate system and the second coordinate system are the same, and the scales of the first coordinate system and the second coordinate system are the same.

It should be noted that the terminal device may obtain a coordinate value of each pixel point in the first target user image area, and then calculate to obtain an average value as a first target coordinate value; the terminal equipment can acquire the coordinate value of each pixel point in the second target user image area, and then calculate to obtain an average value as a second target coordinate value; and then, carrying out subtraction calculation on the first target coordinate value and the second target coordinate value to obtain a position variation, wherein the position variation comprises the size and the direction of the coordinate.

Exemplarily, it is assumed that the first target user image area includes four pixel points, and the coordinate values are pixel point one (2.1, 5.9), pixel point two (2.2, 6.1), pixel point three (2.1, 6.5), and pixel point four (2.3, 6.3), respectively; the second target user image area comprises four pixel points, and the coordinate values are respectively pixel point five (8.6, 10.8), pixel point six (8.9, 10.5), pixel point seven (8.7, 9.8) and pixel point eight (9.2, 11.1). Then, the terminal device may average the coordinate values of the pixel point one, the pixel point two, the pixel point three, and the pixel point four to obtain a first target coordinate value of (2.175, 6.2); and averaging the coordinate values of the pixel point five, the pixel point six, the pixel point seven and the pixel point eight to obtain a second target coordinate value (8.85, 10.55), and then subtracting the first target coordinate value from the second target coordinate value to obtain a position variation value (6.675, 4.35), wherein the direction is from the first target coordinate value to the second target coordinate value.

A second alternative implementation: acquiring a third target coordinate value, wherein the third target coordinate value is the coordinate value of a pixel point corresponding to the central point of the first target user image area; acquiring a fourth target coordinate value, wherein the fourth target coordinate value is the coordinate value of a pixel point corresponding to the central point of the second target user image area; and obtaining the position variation according to the third target coordinate value and the fourth target coordinate value.

The terminal device may establish a third coordinate system for the first user face image and a fourth coordinate system for the second user face image, where the coordinate origins of the third coordinate system and the fourth coordinate system are the same, and the scales of the third coordinate system and the fourth coordinate system are the same.

It should be noted that this alternative implementation is applicable to the case where the first target user image area and the second target user image area are regular image areas. The terminal equipment can acquire a coordinate value of a pixel point corresponding to a central point of the first target user image area as a third target coordinate value; the terminal equipment can acquire the coordinate value of the pixel point corresponding to the central point of the second target user image area as a fourth target coordinate value; and performing subtraction calculation on the third target coordinate value and the fourth target coordinate value to obtain a position variation, wherein the position variation comprises the size and the direction of the coordinate.

Exemplarily, it is assumed that the first target user image area is a circle, a center point of the circle is a circle center, and coordinate values of pixel points corresponding to the circle center are (5.5, 7.9); the second target user image area is a circle, the center point of the circle is the circle center, and the coordinate value of the pixel point corresponding to the circle center is (9.2, 11.1). The terminal device may determine the third target coordinate value to be (5.5, 7.9), determine the fourth target coordinate value to be (9.2, 11.1), and then subtract the third target coordinate value from the fourth target coordinate value to obtain a magnitude of the position change amount to be (3.7, 3.2) and a direction to be the direction from the third target coordinate value to the fourth target coordinate value.

The terminal device can obtain the position variation of the first target user image area and the second target user image area through the two optional implementation modes, and the implementation mode can convert the position variation between the two target image areas into a difference value between the two coordinate values, so that the position variation between the image areas can be more accurately and specifically represented.

107. A second avatar region corresponding to the first avatar region is determined.

In the embodiment of the present invention, the terminal device may determine the second avatar region corresponding to the first avatar region according to the amount of position change.

The first simulated face image region is a region corresponding to the target face feature point in the first simulated face image.

For example, as shown in fig. 4, a schematic diagram of a simulated face image is shown, points 201 to 216 in fig. 4 may be face feature points, as shown in fig. 5, another schematic diagram of a simulated face image is shown, and points 201 to 216 in fig. 5 may be face feature points. Taking the target facial feature point as 212 points as an example, 417 in fig. 4 is a first simulated image region, and 517 in fig. 5 is a second simulated image region.

It should be noted that the first avatar region and the second avatar region are both regions in the first simulated face avatar.

Optionally, the terminal device determines, according to the position variation, a second avatar region corresponding to the first avatar region, which may specifically include two implementation manners:

the implementation mode is as follows: the terminal device can obtain the size ratio (area ratio, perimeter ratio, pixel point number ratio, and the like) between the user face image and the simulated face image, obtain the second position variation on the simulated face image according to the size ratio and the first position variation on the user face image, and add the second position variation to the coordinate value of the first simulated image region to obtain the coordinate value of the second simulated image region.

Illustratively, it is assumed that the terminal device detects that the user face image is 0.7 times of the simulated face image, the first position variation amount is (5.6, 9.0), and the first simulated image region includes four pixel points, namely pixel point one (5.6, 8.4), pixel point two (5.9, 8.1), pixel point three (5.7, 8.6), and pixel point four (5.6, 8.5). Then, the terminal device may calculate that the second position variation is (5.6, 9.0)/0.7 ═ 8.0, 12.9, and then add the second position variation to the coordinate values of the pixel points of the first avatar region, so as to obtain pixel point five (13.6, 21.3), pixel point six (13.9, 21.0), pixel point seven (13.7, 21.5), and pixel point eight (13.6, 21.4). Then the area composed of pixel point five, pixel point six, pixel point seven and pixel point eight is the second analog image area.

The implementation mode two is as follows: the terminal device may directly add the coordinate value of the first avatar region to the first position variation to obtain the coordinate value of the second avatar region.

It should be noted that, this implementation may be applicable to the case where the size of the user face image is the same as that of the simulated face image, that is, the size ratio between the user face image and the simulated face image is 1, and at this time, the first position variation of the first target user image area and the second target user image area may be equal to the second position variation of the first simulated character area and the second simulated character area.

Illustratively, assuming that the first position variation is (5.6, 9.0), the first avatar region includes four pixels, i.e., pixel one (5.6, 8.4), pixel two (5.9, 8.1), pixel three (5.7, 8.6), and pixel four (5.6, 8.5). Then, the second position variation is (5.6, 9.0), and the terminal device adds the coordinate value of the pixel point in the first simulated image region to the second position variation to obtain pixel point five (11.2, 17.4), pixel point six (11.5, 17.1), pixel point seven (11.3, 17.6), and pixel point eight (11.2, 17.5). Then the area composed of pixel point five, pixel point six, pixel point seven and pixel point eight is the second analog image area.

108. And adjusting the pixel value of the second simulated image area to obtain the updated second simulated face image.

In the embodiment of the present invention, the terminal device may adjust the pixel value of the second avatar region according to the pixel value of the first avatar region to obtain the updated second simulated face avatar.

It should be noted that the terminal device may adjust the pixel values of the pixels in the second simulated image region to the pixel values of the pixels in the first simulated image region, and perform the same operation on other facial feature points, so that the terminal device may obtain the updated second simulated facial image.

Optionally, the pixel value includes: one of an RGB value and a YUV value.

Alternatively, the RGB value is a color standard, and various colors are obtained by changing three primary color channels of red (R), green (G) and blue (B) and superimposing them on each other. The colors that can be seen by the naked eyes are formed by mixing the lights of three primary colors of red, green and blue according to different proportions, the RGB values refer to the brightness of the lights of the three primary colors, each light has 256 brightness values, and the brightness values are represented by numbers as 0, 1 and 2.

Alternatively, the RGB color space can be regarded as a unit cube in a three-dimensional rectangular coordinate color system, three axes respectively represent three primary colors of red, green and blue, and any color that can be seen by the naked eye can be represented by a point in the three-dimensional space in the RGB color space.

Exemplarily, as shown in table 1, the correspondence between different colors and different RGB values is shown.

TABLE 1

For example, the color of the lip part of a general user is reddish, and then the RGB value of the pixel point of the lip part may be (250, 0, 0); the color of the pupil part of a general user is black, so that the RGB value of the pixel point of the pupil part can be (5, 3, 0); generally, the color of the tooth part of the user is white, so the RGB value of the pixel point of the tooth part can be (250, 254, 239); generally, the color of the cheek portion of the user is yellow, and then the RGB value of the pixel point of the cheek portion may be (250, 245, 0).

Optionally, YUV is a color coding method, and is mainly used for optimizing transmission of color signals. Compared with the transmission of RGB signals, the great advantage is that it only needs to occupy little bandwidth (RGB requires the transmission of three independent color signals at the same time). Here, "Y" is a baseband signal and represents brightness (Luminance), i.e., a gray scale value. The "U" and "V" represent chromaticity (chroma) which is used to describe the color and saturation of the image for specifying the color of the pixel. U and V are quadrature modulated signals. The YUV color model is derived from an RGB model, and is characterized in that the brightness and the chroma are separated, so that the YUV color model is more suitable for the field of image processing.

Optionally, a conversion relationship is provided between the RGB value and the YUV value.

The conversion relationship is generally shown by the following equation: Y-0.299R + 0.587G + 0.114B, U-0.147R-0.289G + 0.436B, V-0.615R-0.515G-0.100B, R-Y + 1.140V, G-0.394U-0.581V, B-Y + 2.032U.

Then, the terminal device may adjust the pixel value of the pixel point in the second simulated image region to the pixel value of the pixel point in the first simulated image region, that is, adjust the pixel value of the pixel point five corresponding to the pixel point one in the second simulated image region to (250, 0, 0), adjust the pixel value of the pixel point six corresponding to the pixel point two in the second simulated image region to (255, 3, 0), adjust the pixel value of the pixel point seven corresponding to the pixel point three in the second simulated image region to (248, 9, 2), adjust the pixel value of the pixel point eight corresponding to the pixel point four in the second simulated image region to (252, 0, 7), so as to obtain the updated second simulated image region, and perform the same operation on other facial feature points, so as to obtain the updated second simulated facial image.
