Document Type and Number:
WIPO Patent Application WO/2022/111512
Kind Code:
A1
Abstract:
Embodiments of the present application provide a facial liveness detection method and apparatus, and a device. The method comprises: acquiring an infrared image of an object to be detected; extracting a facial local region from the acquired infrared image to obtain a target facial local region image; and determining a grayscale feature of the target facial local region image, and performing liveness detection according to the determined grayscale feature and a pre-trained liveness detection model to obtain a facial liveness detection result of said object. According to the embodiments of the present application, liveness detection based on facial local features is achieved, thereby avoiding the problem of a decrease in the accuracy of the liveness detection result due to that a face is partially blocked.
