Patent ID: 8514940

Claim:
A method for carrying out reliability classification for motion vectors in a video, comprising: partitioning a specified video frame of an input video, and searching motion vectors for a specified block of the specified video frame to generate a block matching error for the specified block; extracting a texture feature of the specified block, the texture feature including an edge feature; and carrying out reliability classification of the motion vectors of the specified block in accordance with the block matching error and the texture feature of the specified block, wherein said motion vectors are classified into three classes of reliable, mismatched and multi-matched, and the partitioning and searching comprises: generating a gray scale image with a lower resolution from the input video; partitioning a center region of the gray scale image of the specified video into multiple blocks with a predetermined size template; searching a block and a position thereof, the block matching error between which and the specified block is the smallest, in a reference frame corresponding to the specified video frame for the specified block, thereby determining a motion vector with the smallest block matching error; and computing the block matching errors between blocks adjacent to the position of the block corresponding to the smallest block matching error and the specified block.
