IMAGE LIVENESS DETECTION METHOD AND DEVICE

Embodiments of the disclosure provide an image liveness detection method and device. The method includes: performing semantic segmentation processing on a to-be-detected image to obtain a first masked image corresponding to a medium image block in the to-be-detected image; performing a biometric recognition on the to-be-detected image to obtain boundary information of a biometric image block in the to-be-detected image; performing pixel processing on the to-be-detected image based on the boundary information to obtain a second masked image corresponding to the biometric image block; obtaining, through calculation, a degree of overlap between the medium image block and the biometric image block based on the first masked image and the second masked image; determining a liveness detection result of the to-be-detected image according to the degree of overlap.
