Hierarchical hybrid shot change detection method for MPEG-compressed video |
摘要 |
The present invention relates to a hierarchical hybrid shot change detection method in MPEG-compressed video circumstances, wherein the method according to the present invention comprises: detecting a shot change candidate region, by hierarchically applying a global color distribution difference among the frames by the color histogram; detecting an abridged shot change candidate region by using the difference of the global color histogram difference among adjacent I, P frames after additionally decoding P frames existed in the detected candidate region; decoding B frames within a abridged shot change detection candidate region at a macro block level in a sequence of the B frames sharing adjacent two anchor frames; determining a distribution characteristic of an intra coded block and a reference pattern type of each B frame in the region; and detecting a hard cut by using the distribution characteristic and reference type.
