Abstract: A method of correcting errors in motion vectors due to camera panning includes identifying an error block that contains an error motion vector out of a plurality of blocks in a current video frame, each block in the current video frame containing a corresponding motion vector. The method also includes calculating an average motion vector value of the motion vectors for all blocks in the current video frame that are not error blocks, identifying a group of effective motion vectors in the current video frame having corresponding motion vector values within a threshold value of the average motion vector value, calculating a panning motion vector value to be equal to an average value of the effective motion vectors, and correcting the error block by setting the motion vector of the error block to be equal to the panning motion vector value.

Abstract: A method of recovering texture information for an error block in a video stream includes applying an edge detection spatial filter on blocks surrounding an error block to detect texture edges, each block containing a plurality of pixels, and identifying first pixels surrounding the error block having texture data above a predetermined threshold value, selecting first pixels and checking the texture data of pixels extending from the selected first pixel in a plurality of predetermined directions for determining a direction of the texture edge, accumulating the edge detection filtering results of pixels that are located on the texture edge in a selected direction, determining the filtering weights corresponding to each direction of the texture edge based on the filtering results of pixels checked in the predetermined directions, and reconstructing the texture of the error block in the spatial domain using weight filtering based on the texture data of surrounding pixels.
