Abstract
In a depth-image-based rendering (DIBR)-based 3D video system, the original 3D video is commonly compressed from the point of the video itself, paying little attention to its contribution to the synthesized virtual view. This paper first proposes a method to divide the original video into different regions according to its contribution to the synthesized view and then proposes to measure the regions using compressive sensing with different measurement rates, leading to a synthesis-aware region-based 3D video coding approach. Experimental results show that our approach can achieve better synthesized quality under the same equivalent measurement rate. Our approach is suitable for the applications when the virtual view is more important than the original views.
