Abstract:

Joint video team (JVT) proposed joint multi-view video model (JMVM) for multi-view video coding (MVC). However, the model does not provide an efficient rate control scheme. In this paper, a new rate control algorithm for multi-view video coding is proposed, which consists of four levels for more accurate bits rate control. In a GOP level, it implements reasonable bit allocation among views based on correlation function. In the frame level, it performs bit allocation based on the hierarchical B-picture bit allocation method. In the MB level, rate control is activated to provide more accurate rate control based on the Laplacian rate-distortion model. Compared to JMVC 1.0 with a fixed quantization parameter, the proposed algorithm achieves better accurate rate control and higher image quality.

Key words: multi-view video coding, rate control, hierarchical B-picture bit allocation, Laplacian rate-distortion model, correlation function
