[0025] In step 201, the user's face is photographed, and the face photographed image is obtained, for example, the contact in the mobile phone is photographed through the mobile phone camera.
[0026] In step 202, the feature data of the face photographed image is extracted. The image is stored in a pixel matrix in the mobile phone, which is actually an integer matrix. Perform mathematical singular value calculation on the integer matrix to obtain the feature data and store it in the mobile phone. .
[0027] In step 203, the feature data of the face photographed image is compared with the stored feature data of multiple user face images to obtain the most similar user face image, for example, the singular value feature of the face photographed image Th...
