Joint depth and texture filtering targeting MVD compression

To meet the requirement of current bandwidth and storage facilities, it is required to further decrease the bitrate of 3D video content. This paper presents a scheme to partially filter different regions of the texture views and depth maps taking into account the characteristics of both of them. A combination of the distance of objects from the cameras and the spatial details of texture within the objects defines the location and strength of the smoothing filter that should be applied to that image. A series of subjective tests was conducted to confirm that the perceived quality of the filtered content remains intact and no quality degradations is introduced by the filtering steps. Finally, objective measurements show a Bjontegaard delta bitrate reduction up to 23.77% with an average of 15.2%.
