An inpainting and optimization method for kinect depth map

Abstract

Depth map acquisition is the key technology in free viewpoint system for multi-view video plus depth (MVD) video format, which can effectively improve the coding efficiency and the quality of synthesized virtual view in 3D video. Acquainting depth map can be accomplished by Kinect depth camera. But hole and noise problems are needed to repair and improve. In this paper, the depth map is inpainted and optimized. Firstly, depth map is clipped from the center of the image and then filled with foreground pixels. Finally, the proposed trilateral filter is used to optimize the image. The experimental results show that the better depth map can be obtained by our method.
