Error concealment (EC) in video communication is becoming increasingly important because of the growing interest in video delivery over unreliable channels such as wireless networks. We propose a spatial EC technique for intracoded frames in video. The proposed algorithm utilizes a small neighborhood of correctly received pixels to find the directions of edges passing through the missing block. The missing block is then restored by multidirectional interpolation along these directions. Experimental results demonstrate that this method is much more efficient than the existing methods and is computationally simple.
