Abstract

Various implementations relate to depth map coding. In one method, a depth coding rate and depth distortion are determined for a coding mode. Based on the value of depth distortion, a correlation coefficient is determined between at least a portion of a video picture and a translated version of the video picture. The video picture is one or more of a video picture corresponding to the depth being coded, or a rendered video picture for a different view. A video distortion is determined based on the correlation coefficient, and is used to evaluate the coding mode. Another implementation determines a multiplier, to be used in a rate-distortion cost, based on pixel values from one or more of a video picture from a particular view or a rendered video picture for a different view.
