Abstract :
Depth map, as important auxiliary information in 3D procession, is used to synthesize virtual view rather than exhibition. Inspired by this, a synthesis-guided depth super resolution (SGDSR) algorithm is proposed. Employing the synthesis error between virtual view and corresponding original one as the criteria, the best super-resolved result is selected among numerous candidate super resolution (SR) results. To fully exploit varying property within different regions of an image, a patch-based SGDSR is further devised in this paper. Experimental results demonstrate the effectiveness of our method subjectively and objectively on both single view and two views platform based on depth-image-based rendering (DIBR).
