Frame-layer bit allocation for multi-view video coding based on frame complexity estimation

Abstract

Current multi-view video coding (MVC) reference model in joint video team (JVT) does not provide efficient rate control schemes. This paper presents a rate control algorithm for MVC by improving the quadratic rate-distortion (R-D) model. We reasonably allocate bit-rate among views based on the correlation analysis. The proposed algorithm consists of three levels to control the rate bits more accurately, of which the frame layer allocates bits according to the frame complexity and the temporal activity. Extensive experiments show that the proposed algorithm can control the bit rate efficiently.
