Description

technical field [0001] The present invention relates to the field of video processing, in particular to a method, device, storage medium and processor for detecting fighting behavior in a video. Background technique [0002] In recent years, with the rapid increase in the number of surveillance cameras, the demand for real-time and efficient analysis and processing of massive videos has become increasingly urgent. In the traditional manual analysis and supervision mode, a security personnel usually needs to pay attention to multiple surveillance video images at all times. Personnel's visual fatigue and distraction can easily lead to a reduction in the ability to judge, resulting in many problems such as false detection or missed detection. In order to detect abnormal behaviors such as fighting and fighting in the first place, and carry out real-time early warning, the intelligent analysis of video has become the focus of research. [0003] For the detection of abnormal beha...
