  4. Abstract:
  5. Block motion estimation is an important field of video processing. This paper presents a new scheme to reach in faster block motion estimation based on motion prediction. The scheme exploits an adaptive filter to predict the block motion from its spatio-temporal motion compensated adjacent blocks, the predicted motion determines the initial candidate block for search methods with biased search center, in special case of partial distortion search, this strategy reduces search time by preventing from complete distortion calculation for more loser candidates, after comparison of three conventional adaptive filters, a normalized least mean square filter with convergence monitoring is recommended for motion prediction from 5 neighbor blocks. Experimental results imply on adaptive filter ability for block motion prediction and its efficiency in reducing the time cost of motion estimation search strategy. © 2006 IEEE
