Abstract
The present invention discloses a motion estimation method for MPEG video sequences. The method makes use of a global motion estimation algorithm to determine a set of dominant motion components. A simultaneous Full Search Block Matching (FSBM) search is conducted utilizing each dominant component for every block in a current frame. The results of each FSBM search are then compared to determine the best motion vector.
