Na Ai · Journal of Northwest University · 2011
Aim To reduce the searching points of motion estimation and improve the search speed.Methods The image motion vector distribution and cross diamond algorithm are studied,the improvement concerns the initial point prediction,earlier termination algorithm,search direction of the search process and the state of moving blocks.Results An improved INCDS algorithm is proposed.Conclusion The results show that the improved algorithm can increase the probability of early termination and reduce the time of motion estimation.
