NEW SORTING-BASED PARTIAL DISTORTION SEARCH ALGORITHM FOR MOTION ESTIMATION
Chou-Chen Wang, Chia-jung Lo · 2005
A new and fast motion-estimation algorithm based on partial block distortion for sorted significant features including bit-plane and absolute mean difference is proposed. The proposed algorithm can obtain relatively accurate motion vectors with a reduced computational load. Simulation results show that the proposed method achieves its MSE performance very close to the fullsearch method, while requiring only 6-8% of the computation needed by the full search. Furthermore, the performance of our method is better than other algorithms based on partial block distortion elimination.
