Fast extraction method for video motion region of interest combining visual characteristics

When the new generation video encoding standard H.264/AVC achieved higher compression ratio and transmission robustness, computational complexity was increased acutely, and was unfavorable in real-time environmental application. Combined the visual perception characteristics and video encoding information, a new extraction method for motion region of interest and optimized coding scheme were proposed in this paper. The simulation results show that the proposed method can obtain video motion region of interest accurately, and the optimized coding scheme can achieve reduction of 53.11% encoding time on average with almost the same quality and bit-rate compared with H.264/AVC, and can be unified with other H.264/AVC fast coding technology to enhance the encoding speed further, in order to satisfy the heterogeneous networks and diversity terminal environment.
