Abstract:

When bit errors occur during, transmission and cannot be corrected by an error correction scheme, error concealment is needed to mask the damaged image at receiver. In this paper, a content-adaptive spatial error concealment algorithm is presented. By using edge information extracted from the surrounding blocks, the proposed algorithm firstly classifies each error block (EB) into one of three categories with different contents. And then the EB is reconstructed by appropriate methods to the category of it belonging to. Experimental results demonstrate that the proposed algorithm obtain good subjective quality whether the content in the EB is with high or low details.
