MULTIPLE-CANDIDATE MOTION ESTIMATION WITH ADVANCED SPATIAL FILTERING OF DIFFERENTIAL MOTION VECTORS |
摘要 |
A system and method of performing motion estimation in a video encoder is enclosed. The system and method include calculating one or more candidate motion vectors for each macroblock of a video image to form a list of candidate motion vectors, calculating a second one or more candidate motion vectors using a sub-region of at least one macroblock of the video image to include in the list of candidate motion vectors, and comparing the calculated candidate motion vectors of a first macroblock with the calculated candidate motion vectors of at least one sub-region of the first macroblock to provide the estimated contribution to the candidate motion vector of the macroblock. The calculating a second one or more candidate motion vectors using a sub-region of at least one macroblock may include using an approximation different from the calculating one or more candidate motion vectors for each macroblock.
