Variable size motion estimation （ME） and disparity estimation （DE） are employed to select the best coding mode for each macroblock （MB） in the current joint multiview video model （JMVM）. This technique achieves the highest possible coding efficiency, but it results in extremely large computation complexity which obstructs the multiview video coding （MVC） from practical application. This paper proposes an adaptive early termination of fast mode decision algorithm for MVC. It makes use of the coding information of the corresponding MBs in neighbor view based on inter-view correlation to early terminate the mode decision procedure. Experimental results show that the proposed fast mode decision algorithm can achieve computational 50% computation saving with no significant loss of rate distortion （RD） performance.
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 analysisl 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.
