Video behavior detection methods, video behavior devices, computer equipment, and computer-readable storage media

Abstract

The term refers to methods for detecting video behavior, video behavior detection devices, computer devices, and computer-readable storage media. This video behavior recognition method includes: extracting video image features from at least two frames of target video images (202); performing adjustments on the spatial features of video image features to obtain intermediate image features (204); Merging, based on the prior information, the temporal characteristics of the intermediate image characteristic with the associated characteristic that corresponds to the temporal characteristic, to obtain the merged characteristic, in which prior information is obtained according to the changing information of the intermediate image characteristic over time, and the associated characteristic is obtained by performing centralized processing on the temporal characteristic (206); perform the adjustment of the temporal feature contribution on the merged feature to obtain the behavior recognition feature (208); and perform video behavior recognition on the basis of the behavior recognition feature (210),
