【 摘 要 】

In 3D display systems, depth image-based rendering (DIBR) is the most common technique to generate virtual images through reference views. However, disoccluded hole filling problems remain a challenging issue and the quality of the synthesized views depends on the hole filling process. Image inpainting-based hole filling is a popular approach to fill the hole region but the conventional method generates annoying artifacts along the boundaries of the foreground. This paper presents an efficient hole filling method that fills the boundary with the high visual quality. The proposed method fills the background region prior to the boundary region by using the depth values. Also, based on the boundary decision, boundary regions are filled with background-related data by clustering the pixels on the boundary into background and foreground. Experimental results show that the proposed method has reduced boundary artifacts and achieves higher visual comfort.
