| description | The embodiment of the invention discloses a living body detection method, a device, electronic equipment and a storage medium. According to the embodiment of the invention, the method comprises the steps of when a living body detection request is received, obtaining reflected audio signal and video data of a to-be-detected object, carrying out signal processing and time-frequency analysis on the reflected audio signal to obtain time-frequency information of the processed audio signal, and extracting the motion track information of the to-be-detected object from the video data; respectively performing feature extraction on the time-frequency information and the motion track information to obtain audio features and motion features of the to-be-detected object, then calculating first global attention information of the to-be-detected object according to the audio features, and calculating second global attention of the to-be-detected object according to the motion features; and fusing the first global attention |
