The new video compression standard H.264 provides better compression of video images than MPEG-4,but it takes a more complicated algorithm as expenses.In order to reduce the search points and improve the search rate,a directional search pattern is designed,and an improved cross-diamond search algorithm is proposed.The Algorithm adopts a series of skills,which are composed of prediction of initial search point,search pattern and auxiliary search points.Experimental results show that the improved cross-diamond algorithm can increase the search rate while keeping the similar PSNR.
