Abstract:

The virtual viewpoint synthesis technology based on depth images is an emerging cross-technology in 3D video information processing, virtual reality, and computer graphics. First, the principles of 3D video virtual viewpoint rendering（or synthesis） are introduced. Next, the generation mechanism of the occlusion, artifacts, and holes generated by the virtual viewpoint synthesis is analyzed. Then, the classifications and summarizations of the process of filling holes based on the background reconstruction, image completion, and the restored method based on related images, and the methods to improve the quality of the composite image are listed. Finally, it summarizes and prospects that deep learning and other technologies are the future research directions of virtual view synthesis technology.

Key words: virtual viewpoint synthesis, 3D video images, image artifacts, image holes
