Effect of a synthesized depth view on multi-view rendering quality

Abstract

In general, a depth image in a multi-view video plus depth (MVD) format is employed as additional data to synthesize a virtual texture view. In this paper, the proposed method generates a virtual depth view through depth view synthesis and then adaptively uses the synthesized virtual depth view during encoding, according to an evaluation on effect of the synthesized depth view on the multi-view rendering quality. Experimental results demonstrate that the proposed method significantly reduces a depth image coding bit rate without degrading the rendering quality.Index Terms -Depth map coding, depth view synthesis, multi-view video plus depth (MVD), rendering quality.
