Figure FDA0002024487980000031
mxythe RGB value of the pixel coordinate point of the first face image is shown, x is the length of the first face image, and y is the width of the first face image of the article;
the processing unit matrixing the second face image to be N (a, b), and establishing the following matrix:
Figure FDA0002024487980000041
nabthe RGB value of the pixel coordinate point of the second face image is shown, a is the length of the second face image, and b is the width of the second face image;
then, the general identification characteristic of the first face map is used
Figure FDA0002024487980000042
Rotating, translating and stretching the second face image for the standard to enable the directions, the orientations and the sizes of the faces to be consistent;
Figure FDA0002024487980000043
wherein N isnew(x, y) is a new matrix of the second face map obtained with the generic features as the criteria,
Figure FDA0002024487980000044
in order to obtain the scaling factor,
Figure FDA0002024487980000045
is a rotation matrix, i is the rotation direction, j is the rotation angle,
Figure FDA0002024487980000046
is a translation matrix, q is the horizontal translation degree, and p is the longitudinal translation degree;
converting the first face image and the second face image into matrixes under the unified standard, solving characteristic values and characteristic vectors of the matrixes of the first face image and the second face image by using a similarity diagonalization principle, and forming a characteristic matrix of each obtained characteristic vector of each item image to be recorded as T1kAnd T2lK and l represent the second eigenvector in the matrix, and the similarity between each eigenvector in the first matrix and all eigenvectors in the second matrix is calculated by using a cosine similarity plus correction method as follows:
Figure FDA0002024487980000047
wherein w is T1kThe total number of medium feature vectors, v being T2lC is T1kAnd T2lThe number of the same elements in f is only T1kIn the presence of an element in T2lIs absent, d is only at T2lThe element in (A) is present in T1kIs not present, delta is a correction coefficient;
degree of similarityAnd the first face image and the second face image which are larger than the first preset value are in corresponding states.
