ABSTRACT: In order to reduce the execute time of EPZS (Enhanced Predictive Zonal Search) algorithm on
the premise of ensuring the image quality, an accurate judgment of unifor mity of motion vectors was made using
rotated Cartesian coordinate system in this paper, and different optimize methods were proposed according
to ...
