Non-reference virtual view quality evaluation of MVD

The quality of virtual view based on multi-view video (MVD) plus depth format is often evaluated by PSNR or subjectively judged.However,due to synthesizing arbitrary view images,the virtual view images mostly have no reference images and are only assessed using non-reference.Virtual view images synthesized by depth estimation reference software (DERS) and view synthesis reference software (VSRS) often accompanied with blockiness and other distortions on the edge.In addition,matching level for the depth map and the corresponding texture maps of left and right views also affects the quality of the virtual view.This paper compares the edge similarity of the depth and the corresponding texture maps which generate the intermediate virtual view and combined with the virtual view’s blockiness which causing blur to evaluate the quality of the virtual view.Experiment results show that the proposed method can reflect the quality of the virtual view better.
