First Claim
1. A method for face image recognition, comprising:
- generating one or more face region pairs of face images to be compared and recognized;
forming a plurality of feature modes by exchanging two face regions of each face region pair and horizontally flipping each face region of each face region pair;
receiving, by one or more convolutional neural networks, the plurality of feature modes, each of which forms a plurality of input maps;
extracting, by the one or more convolutional neural networks, one or more identity relational features from the input maps to form a plurality of output maps which reflect identity relations of the compared face images; and
recognizing whether the face images belong to the same identity based on the identity relational features of the face images.
