摘要: A key frame representative of a sequence frames in video file is selected. The divided into shots, sequences captured by single continuous operation the camera, detecting shot boundaries. Shot boundaries are detected measuring changes motion activity between using measures pixel intensity and histogram differences frames. most interesting selected activity, spatial skin color length. activity.
