Embodiment Construction
[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0040] figure 1 An anti-spoofing method in a face recognition system shown, the specific steps are:
[0041] Step S1, acquire images and perform normalization processing:
[0042] Obtain an RGB image through the camera device, and then input the acquired RGB image to the cascade CNN face detection module; the face detection module performs face detection on the RGB image, and if a face is detected, the image of the face area in the figure is The input is given to the deep neural network to locate the key points of the face, and by calculating the affine transformation from the key points to the standard key points, the face pictures in different poses are transformed into the face pictures in the standard pose;
[0043] Step S2, feature extraction stage:
[0044] The following seven features are extracted:
[0045] a. Color diversit...
