Analysis and improvement for EPZS motion estimation algorithm
Tian Xiu-hua · Computer Engineering and Applications Journal · 2012
In analysis of the H.264 video coding standard recommended by the motion estimation core algorithms EPZS,against the lack of real-time algorithm for motion estimation,the improved methods of EPZS are proposed for the initial search window center and calculating the criterion of condition termination,and the five test sequences are selected for experiments in H.264 encoder and the reference model JM10.1.Experimental results show that the improved algorithm with the original algorithm,the reconstruction image quality and bit rate close to the case,motion estimation time reduces 29.314% on average,reducing the complexity of the algorithm to improve the coding of real-time.
