View synthesis is a technique to generate images/videos in a virtual viewpoint. In this paper, the dis-occlusion/hole problem in view synthesis is resolved from the temporal domain. By the fact that dis-occlusions belong to the background, firstly we build an online background under a newly designed Switchable Gaussian Model (SGM), owning to its computationally simplicity and scene adaptivity. Then, real textures in the dis-occlusions are able to be recovered with the built background. Experimental results have verified the improvements in rendering quality and computation complexity by comparing to the conventional spatial filling methods and other temporal filling methods.
