Abstract

The invention relates to living body detection of a biological recognition technology, and provides a living body video picture processing method and device, computer equipment and a storage medium. The method comprises the following steps: receiving a detection request of a living body video and storing the living body video into a memory; obtaining an original living body video data packet, andcalculating the number of pictures in the original living body video data packet; performing frame extraction on the pictures in the original living body video data packet according to the number of the pictures in the original living body video data packet to obtain a target picture; decoding the target picture to obtain a decoded target picture; and feeding back the decoded target picture to a bottom layer interface. The device, the computer equipment and the storage medium are all used for processing the living body video pictures based on the steps of the method. According to the method, intermediate processing links are reduced by directly operating in the memory, the living body video arrangement processing performance is improved, the processing speed of living body video detectiondecoding videos is increased, and the performance loss of a GPU is reduced.

Description

technical field [0001] The invention relates to the technical field of biometric identification, in particular to a video image processing method, device and readable storage medium in living body detection. Background technique [0002] As a mature biometric technology, portrait recognition has been widely used in finance, education, public security, social services, e-commerce and other fields. However, human faces are easily duplicated with videos or photos for fraudulent identification, making security problematic. Video liveness detection is currently the main solution to this security problem. [0003] In the prior art video liveness detection, it is necessary to decode the video into pictures and sounds, while the liveness detection only needs to detect the decoded pictures, and does not detect the decoded sounds. When detecting the confidence level of liveness in pictures, generally not all video pictures are detected, but only about 3 to 6 seconds of video are det...
