| 摘 要： | 针对自由视点三维电视系统中深度估计不准确将给后续多视点深度编码和虚拟视点绘制带来困难的问题，提出一种面向编码和绘制的多视点图像深度估计算法。首先对初始深度进行一致性检查，并采用自适应匹配误差策略删除不可靠的匹配以减小初始深度的误匹配。然后根据融合准则将多幅参考深度图合成为一幅深度图以提高深度图的精度。最后，采用多边滤波...

| Abstract: | To measure the influence of depth estimation error on depth coding and virtual view rendering in a free-viewpoint television(FTV) system,a multi-view depth estimation is proposed to solve the problem for coding and view synthesis.Firstly,the consistency of initial depth is checked and the influence of initial miss-matches is minimized by introducing an additional adaptive matching error that penalizes the unreliable matches.Then according to specific criteria,the multi-reference depth maps are m... |
