Embodiment Construction
[0062] The present invention will be further described below in conjunction with accompanying drawing.
[0063] Such as figure 1 As shown, a massive face library retrieval method based on human-machine collaboration, specifically includes the following steps:
[0064] Step 1: Preprocessing of Pedestrian Surveillance Video
[0065] A number of surveillance videos from different corners of the campus were randomly selected, and the frame rate of the surveillance video was 60 frames per second; 2 frames per second were selected from the surveillance video for analysis, and the Retinaface model was used to detect the faces and key points of their facial features, and then Face alignment is carried out through facial feature key points; use the Arcface model to maximize the face classification interface in the angle space, and perform face recognition to extract face feature vectors, specifically:
[0066] Step 1-1: In order to improve the video face detection speed, perform fram...
