Embodiment Construction
[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0039] please see figure 1 , the technical solution adopted by the present invention is: a method for extracting video clips of people based on multi-target motion tracking, which first extracts video clips where moving objects appear, and then performs identification of people on the extracted video clips. The main steps are: use the frame difference method to detect the moving target in the video frame image to be tested; track the motion trajectory of the detected moving target; frame the tracked moving target; extract the video according to the start frame and end frame where the moving target appears Segments; Person identification is performed on extracted video segments.
[0040] please see figure 2 , in this specific embodiment, the moving object detection is performed from the third frame of the video to be tested, assuming that the...
