[0035] In order to better illustrate the present invention, the public behavioral data set UCF101 is taken as an example below. In this example, k=3 is used to segment the entire video, that is, three time-segmented networks are used, and in each network Select M=3 layer features, k and M can be adjusted according to the actual situation in the specific implementation.
[0036] figure 2 It is the overall model diagram after dividing the entire video into three sections in chronological order;
[0037] image 3 It is an overall model diagram (single time segment) of the present invention;
[0038] image 3 The algorithm model diagram of the present invention representing a single time segment, combined with figure 2It can represent the complete algorithm flow chart in the present invention. The algorithm uses RGB pictures and corresponding continuous optical flow pictures as input, wherein the RGB frames obtained from the video are input into the spatial flow network, and...
