摘要

A face liveness recognition method includes: obtaining a target image containing a facial image; extracting facial feature data of the facial image in the target image; performing face liveness recognition according to the facial feature data to obtain a first confidence level using a first recognition model, the first confidence level denoting a first probability of recognizing a live face; extracting background feature data from an extended facial image, the extended facial image being obtained by extending a region that covers the facial image; performing face liveness recognition according to the background feature data to obtain a second confidence level using a second recognition model, the second confidence level denoting a second probability of recognizing a live face; and according to the first confidence level and the second confidence level, obtaining a recognition result indicating that the target image is a live facial image.

說明書

In one embodiment, the feature map output by the convolution layer of the recognition model can better reflect the features extracted from the corresponding input image. Therefore, the confidence level of the target image being a live facial image can be obtained by classifying on the fully connected layer according to the feature map that reflects the features, and recognition accuracy of the recognition model is ensured.
