摘要 针对虚拟视点合成中存在的伪影和空洞问题,提出一种基于深度图像的视点绘制新方法.该方法首先使用视点同步生成机制得到虚拟视点的图像和深度信息,并根据深度信息擦除背景伪影;其次,通过基于深度的空洞填补和边界处理方法进一步消除视点图像中的空洞和前景边缘失真.实验结果表明,与MPEG的3DV/FTV标准参考方法相比,该方法生成的虚拟视点PSNR值提高了2dB. Against the ghosting and holes problem,this study proposes a novel method of depth-image-based view synthesis.First,we present a simultaneous rendering mechanism to generate the depth and image of virtual view at the same time,and then erase the ghosting by the depth comparison.Secondly,by means of depth-based hole filling and boundary treatment,we remove the holes in virtual view and boundary distortion.Experimental results show that,the PSNR of virtual view using this method is 2dB higher than that using ...
