Multi-regions in the scalable video coding method

Human visual system function is non-uniform to visual perception. Normally, people tend to focus on one or more specific moving objects while watching video. In addition, video transmission is flawed due to heterogeneous networks and limited bandwidth. Therefore, how to transmit the content of interests more efficiently becomes a growing concerning topic. This paper proposes a method of multi-region in the scalable video coding. In the proposed method, the multi-region firstly get through the particle tracking filters, and then it is implemented motion estimation to each region and finally allocated bit-rate under the 3D-wavelet scalable video coding model. Experimental results show that the performance of our approach is effective, in particularly the situations of lower bit rate. The approach is particularly suitable for mobile video communication, and video surveillance on intelligent vehicle.
