【Abstract】 To achieve more efficiency for video sequence coding, an advanced cross-diamond fast block motion estimation search algorithm is presente in this paper. The proposed algorithm is carried out by predicting motion vector, adjusting search- ing window’s size and using cross-diamond search. Experimental results show that the algorithm can reduce computation sig- nificanly, increase computing speed greatly, providing good reconstructed video quality.更多还原
