New spatial error concealment method based on match of boundary subsection
基于边界分段匹配的空域视频错误隐藏算法

A new spatial error concealment method based on match of boundary subsection is proposed to reconstruct the missing block with the intact pixels surounding it.It first estimates edge of each block boundary.Then according to it,the boundaries are partitioned into several subsections.To each subsection,we search the best match pixs in the vicinity of the subsection to recovery it. Concealment is accomplished by reconstructing each boundary repeatedly according to a suitable strategy. Experimental results showed that our algorithm can achieve good directional interpolation concealment results in both visual efect and PSNR.
