To improve coding efficiency and visual quality in video coding, adaptive loop filtering (ALF) methods using directional features to classify pixels for filter adaptation have been proposed in the literature. However, the associated complexity has been identified as an obstacle for realistic hardware implementation and deployment. This paper presents an ALF design, which efficiently classifies video...
Video representations that support view synthesis based on depth maps, such as multiview plus depth (MVD), have been recently proposed, raising interest in efficient tools for depth map coding. In this paper, we derive a new distortion metric that takes into consideration camera parameters and global video characteristics in order to quantify the effect of lossy coding of depth maps on synthesized...
