基于图像金字塔修复的虚拟视点绘制
Virtual Viewpoint Rendering Based on Image Pyramid Inpainting
摘要
Abstract
Aiming at the problem of the holes caused by exposing regions in virtual viewpoint rendering,this paper proposes a virtual viewpoint rendering method based on image pyramid inpainting.The viewpoint warping equation is utilized to generate a virtual viewpoint.The image pyramid method is employed to restore holes inside the warped view.Depth information is incorporated into the cost function for Gaussian plus zero-canceling filter and down-sampling,low resolution image can be up-sampling,the expanded image information can be used to fill the holes.Experimental results show the proposed algorithm has superiority in both subjective details and the results of Peak Signal to Noise Ratio(PSNR),and virtual viewpoint of image rendering has not distortion,it can restrain the generation of false image in the edge.关键词
