| Abstract: | As motion estimation is vital to image coding algorithm,the block matching algorithm based on MAD (minimum absolute difference) is extensively used.But it also shows its deficiency in motion vector coherence and antinoise ability.In this paper,a new algorithm is proposed,which pays more attention to the correlation of neighboring blocks.This new algorithm achieves better results as shown by the experimental comparison. |
