Abstract:
In one embodiment the present invention includes a digital image processing method for concealing errors. The method includes determining error pixel locations based on motion vectors and determining if the error pixel locations in a current frame are on an edge of an object in the current frame. If an error pixel location is on an edge, then a search of pixel values is performed in the current frame along the edge for a replacement pixel value. If the error pixel location is not on an edge, then a search of pixel values is performed in a region adjacent to the edge for the replacement pixel value.
