A homogenizing filter for depth map compressive sensing using edge-awarded method

Abstract

The edge-awarded method for depth map compressive sensing (CS) was proposed. The edge-awarded depth map CS showed better visual quality than H.264/AVC which are widely used. This method can reconstruct efficiently the boundary of objects. However, this makes staircase artifact around edges unfortunately. These artifact makes pixel value around edge to distorted value. Edge is most important information in depth map. So, this artifact cause really critical problem especially when image rendering process. In this paper, to eliminate staircase artifact generated by edge-awarded depth map CS, we proposed a homogenizing filter to relive the staircase effects. The experimental results show the proposed filter provides better visual image quality than compressive sensing using edge-adaptive method and H.264.
