Spatial error concealment method based on tensor voting
摘要
Abstract
As the existing spatial error concealment algorithms is lack of the recovery accuracy in complex texture areas, a spatial error concealment method based on tensor voting was proposed, which extracted structural information by using tensor voting. On this basis, an improved spatial error concealment algorithm which combined with the traditional algorithms was further proposed. Firstly the lost marc blocks were classified into three categories, and then the appropriate concealment method was chose to recover the lost macro blocks according to the type of lost macro blocks. Experimental results show that the proposed method improves the recovery accuracy effectively and avoids the edge disorder phenomenon, especially in the region with more complex texture, the subjective and objective quality of concealed image is improved greatly.关键词
