Method and apparatus for determining motion vectors in dynamic images

摘要: In order to increase the speed of motion vector calculation characteristic pixels from a macroblock are selected and control sum is calculated only those while coordinates using all values in macroblock. one embodiment rows re-odered ascending value serveral equidistant selected. The columns then re-ordered increasing several provide pixels. second selectred drecreasing deviation mean row. arranged further on basis decreasing absolute column average. third divided into sub-blocks single having maximum or minimum for that sub-block. Selection alternates block block.
