摘要:Rate control is one of important tools in multi-view video coding (MVC). This paper presents a new rate control algorithm for MVC by analyzing the rate allocation proportion among different types of views. The proposed algorithm is performed on three levels, that is, view level, group-of-pictures (GOP) level and frame level. Firstly, we reasonably allocate bit-rate among views based on the statistical analysis in the view level. Then, in the GOP level, the initial quantization parameter (QP) of each GOP is set according to the QP values of B frames. Finally, the frame complexity is used to regulate the target bit for each frame. Experimental results show that the proposed algorithm can accurately control bit-rate to satisfy the requirements of multi-view video systems.
