Abstract

A block loss recovery technique based on multiple edge detection is presented in this paper. A new spatial interpolation algorithm based on multiple edge detection is proposed. This approach improves the capability into reliability to recover multiple edge intersection contents in the corrupted block. Experimental results demonstrate that the proposed method has better performance than traditional linear interpolation method and the conventional interpolation method which is based on edge detection.
