ABSTRACT:
A method and system for performing motion estimation for a frame associated with a video signal. The method includes receiving at least a reference frame, a first frame, and a second frame, and providing a first plurality of vectors. The first plurality of vectors intersects the first frame within a first block and intersects the reference frame within a first plurality of blocks respectively. Additionally, the method includes determining a second plurality of vectors based on at least information associated with the first plurality of vectors. The second plurality of vectors intersects the second frame within a second block and intersecting the reference frame at a plurality of locations. Moreover, the method includes processing information associated with the plurality of locations, and determining a plurality of search areas corresponding to the plurality of locations in the second frame.
