Key frame selection is the process to select the most representative frames of a long video sequence. The paper describes a new algorithm for determining key frames in a video shot. We use macroblock (MB) type and motion vector information of MPEG compressed video to determine the local maxima of visual content change in a shot, i.e. the frames that are most noticeable to the viewer. This algorithm exploits the important cue of the intensity of motion activity and visual content change within a… CONTINUE READING
