Correction Algorithm for False Depth Values in Generating Point Cloud

Various multimedia systems have adopted the techniques related to point cloud in order to provide the immersive sense to users. In those systems, the depth values are very crucial because those dominantly affect the sense of reality. To increase the quality of point cloud by enhancing the depth images, various algorithms have been proposed. Whereas conventional methods remove the invalid depth information in construction of point cloud, we propose an algorithm to correct the invalid depth value. Simulation results show that the proposed algorithm outperforms other conventional techniques objectively and subjectively.
