Changsheng Xie · Jisuanji yingyong yanjiu · 2007
Improved cross-diamond search algorithm(ICDS) was proposed.Search steps of using small cross-search pattern to find small motion vectors in initial phase and directional diamond search pattern to further determine search large motion vectors in subsequent steps were brought forward.Finally,architecture of the algorithm for implementation was introduced and performance was analyzed.
