Improved video compression for indoor video surveillance application

This paper describes a new method to improve the compression ratio of H.264 when used in indoor video surveillance with static camera. Motion detection technique is introduced into H.264. The proposed motion detection algorithm consists of motion detection of successive frames and background frame subtraction. The motion detection of temporal frame is used in this system for detecting whether there are continuously moving objects between two consecutive frames. The background frame subtraction is used for detecting moving objects in current frame. Test results show that bit rate of video surveillance system can be reduced from 10% to 15% for the selected test sequences.
