Abstract:

An algorithm for detecting the moving object on H264/AVC compressed domain is presented.Firstly,motion fields and macroblock partition type are extracted from the compressed video,in which the noise vectors are removed by median filter,and some fake moving block are excluded.Then,the moving regions are marked with adaptive threshold.Finally,the accurate moving object is recognized using the feature of the marked moving regions.This algorithm is easy to implement and suitable for intelligent monitoring and video analysis.Test results show that the detecting effect is good even without decoding all the compressed bit stream.

Key words: moving object detection;H.264;compressed domain
