GOP STRUCTURE EXTRACTION METHOD FOR FLEXIBLY DRAWING A GOP SIZE

摘要

PURPOSE: A GOP structure extraction method is provided to prevent a GOP structure from being cut in the boundary of the maximum GOP size. ;CONSTITUTION: A motion feature vector is denormalized in a final GOP(Group Of Picture) among GOPs drawn within the previously acquired maximum GOP size(S221). A motion feature vector for a frame within all current maximum GOP sizes is calculated(S222). A motion accumulation vector is obtained(S224). The index of a motion accumulation vector having the minimum level normalization size is selected(S225). The motion feature vector and the motion accumulation vector are reset by reflecting the selected index(S226).;COPYRIGHT KIPO 2011
