Abstract
In this paper, a new mode decision scheme is proposed for depth map coding in 3D-AVS. The novelty of the paper mainly contains the following two points. Firstly, an improved distortion estimation model of synthesized views is proposed. Secondly, for the mode decision of depth map coding, the distortion is represented to be the weighted sum of depth distortion and estimated distortion of the synthesized view. We proposed a new scheme to derive the weighting factors adaptively based on the disparity. Then the distortion is utilized to calculate the rate distortion cost for mode decision. Experimental results demonstrate that the proposed scheme achieves remarkable performance improvement in 3D-AVS. The average BD-rate gain is about 12%.
