Spatial Error Concealment Based on Judgement on Edge Information
An efficient spatial error concealment algorithm is proposed for corrupted image by transmission losses in this work. Firstly, information of edges in the neighboring blocks is extracted by judgements on which edges may traverse the loss block. Then, all detected edges are divided into relevant and irrelevant edge. Subsequently, one or more directions for interpolation can be selected from the relevant edge set by minimizing the boundary pixel difference for each direction. The method improves the capability of recovering more high-detailed contents of lost block with low complexity. Experimental results demonstrate the better performance of the proposed methods as compared to previous techniques.
