The method and apparatus using video detection fighting behavior

The present invention relates to a method and apparatus for detecting fighting behavior using video, the method comprising the steps of: obtaining a plurality of successive video frames from the video; extracting foreground motion from a plurality of successive video frames; motion detected from the foreground moving object; if there are at least two moving object is determined in a plurality of successive video frames, if present, proceed to the following step, and if not, it is determined fighting behavior does not occur; calculating a plurality of successive video frames of each moving object to each other the distance between, if the distance is less than a specified threshold, proceed to the following step, if the distance is not less than the specified threshold value, it is determined fighting behavior does not occur; calculating a plurality of successive video frames of the moving object to cover at least two the size of the change in intensity of the area of ​​the smallest rectangle area determines whether fighting behavior; wherein the area is a change in the intensity parameter indicates the rate of change when the area is continuously changed. The present invention can effectively reduce the false alarm rate detection fighting behavior.
