Operation 202, detecting a deformation profile of the image including the face.

In particular, the image can be taken by an electronic device with a camera. The image contains a human face. The image can be an image stored in an album or on a network. The deformation profile refers to a facial contour formed by deformation of a facial contour caused by refraction or the like of the face. Refraction refers to the refraction of the area of the lens due to myopia or farsighted lenses.

The image can be detected by a machine learning model to obtain a deformation profile containing the face in the image. In order to identify by machine learning model, the computer device needs to collect normal facial contour samples and facial contour samples containing deformation contours as training samples for machine learning, and train machine learning models through training samples to obtain machine learning of facial contours. model.

In one embodiment, the computer device can also recognize facial features in the image through a key feature point extraction algorithm for the face. The facial features may include several features such as the eyes, mouth, nose, and eyebrows. The face key feature points may include 2 eyeball center points, 4 eye corner points, 2 nozzle midpoints, and 2 mouth corner points. The computer device can use the susan operator to extract the edge and corner features of the local region. The principle of the Susan operator is to use a circular area with a radius of pixels as a mask to examine how the pixel values of all points in the region of the image coincide with the values of the current point. In other embodiments, the computer device can also detect the facial contour and the deformation contour of the face by using an edge detection operator such as sobel or canny.

In operation 204, a deformation trend of the deformation profile is determined, and a corresponding deformation operator is selected according to the deformation trend.

Specifically, after the computer device detects the deformation profile including the face, the shape of the deformation profile can be obtained. The computer device compares the shape of the deformed contour with the shape of the reference facial contour, and whether the deformation trend of the deformed contour is reduced or expanded. The reference face contour refers to a preset face contour as a standard.

In one embodiment, the operation 204 includes: when determining that the deformation trend of the deformation profile is reduced, selecting a first deformation operator; and when determining that the deformation trend of the deformation profile is expanding, selecting a second deformation calculation child.

Specifically, the computer device may pre-establish a correspondence relationship between the deformation trend and the deformation operator, and after detecting the deformation trend, obtain a corresponding deformation operator from the corresponding relationship between the deformation trend and the deformation operator according to the deformation trend. A deformation operator is a parameter that performs a deformation operation on an image.

Operation 206, identifying a facial contour of the face in the image.

In particular, the computer device may employ a machine learning model to identify facial contours in the image. The machine learning model is obtained by training the training samples in advance, or by extracting key feature points of the face.

Operation 208, curve fitting the deformed contour of the face according to the facial contour to obtain a fitting curve.

Specifically, the computer device may fit the corresponding reference facial contour according to the remaining contours remaining in the facial contour except the deformed contour. The computer device obtains a curve contoured face contour, that is, a fitting curve, according to the reference face contour and the detected facial contour in the image.

Curve fitting can use scatter points other than the deformed contour in the contour of the face, select the appropriate curve type for variable transformation, make the two variables after the transformation have a linear relationship, and find the linear equation and variance according to the least squares method, and straighten the line. The equation is converted to a function expression about the original variable.

In operation 210, the deformation operator is adjusted according to the fitting curve and the deformation profile to obtain an updated deformation operator.

Specifically, the computer device adjusts the deformation operator according to the difference between the fitting curve and the deformation profile to obtain the updated deformation operator. The deformation operator can be an affine transformation matrix. Each affine transform corresponds to a multiplication of a rectangle and a vector. Affine transformations can be achieved through a series of atomic transformations, including translation, scaling, flipping, rotation, and miscutting.

For example, the simulation transformation is represented by a 3 × 3 matrix, the last of which is (0, 0, 1). The transformation matrix transforms the original coordinates (x ₁ , y ₁ ) into new coordinates (x ₂ , y ₂ ). The original coordinates and the new coordinates are adjacent to the three-dimensional column of the last behavior (1), and the original column vector is multiplied by the transformation. The matrix gets a new column vector, as in equation (1).

In order to change the deformation profile into a fitted curve, the deformation profile can be obtained by translational transformation. The transformation matrix of the translation transformation can be

Where tx=x ₂ -x ₁ and ty=y ₂ -y ₁ . (x ₂ , y ₂ ) is the coordinate of a point on the fitted curve, and (x ₁ , y ₁ ) is the coordinate of the corresponding point on the deformed contour.

Operation 212, deforming the deformation profile by using the updated deformation operator.

Specifically, the computer device deforms the deformation profile by the updated deformation operator to obtain the corrected contour.

The image correction method in the embodiment of the present application detects the deformation profile of the face in the image, selects a corresponding deformation operator according to the deformation trend of the deformation profile, detects the contour of the face, and formulates the deformation profile according to the contour of the face. The fitting curve is obtained, and the deformation operator is adjusted according to the fitting curve and the deformation contour to obtain the updated deformation operator, and the deformed contour can be corrected according to the updated deformation operator to obtain the corrected facial contour and improved. The imaging effect of the face.

It should be noted that identifying the facial contour in the image may precede the operation 202.

In one embodiment, including the deformation profile of the face in the detection image comprises: acquiring the deformation profile including the face according to a color of the skin.

Specifically, face detection based on skin color may include pre-processing, skin color segmentation based on skin color model; connected domain analysis, face region localization. The preprocessing can use Gaussian filtering and histogram equalization. The skin color model can adopt a color model of the YCbCr space, where Y refers to luminance information, and Cb and Cr are chrominance information. The computer device establishes a Gaussian model of the skin color according to the mean and variance of the skin color, and obtains a face probability map through the Gaussian model of the skin color, and uses the binarization to obtain the face color binary image. The computer device can perform connected domain analysis on the input image to obtain a minimum circumscribed rectangle of the binary image, that is, a face region. Specifically, the computer device first displays the pixels in the binary image that meet the preset connection rule by the same label, obtains the connected area contour of the binary image, and obtains the minimum circumscribed rectangle of the connected area. Methods for connecting domain tags include pixel notation, line notation, and region growing. Taking the eight-field pixel marking method as an example, 1) judging the leftmost, upper left, uppermost, and upper right points in the eight fields of this point, if there is no point, it indicates the beginning of a new area; 2) if this point The leftmost point in the eight fields, there are points on the upper right, mark this point as the smallest mark in the two, and modify the big mark as a small mark; 3) If this point is the top left of the eight fields, the top right A little, mark this point as the smallest point in the two, and modify the big mark as a small mark; 4) Otherwise mark the point as one of the four in the order of leftmost, upper left, uppermost, upper right.
