Key frame is a simple yet effective form of summarizing a long video sequence. In this paper, we present a novel key frame extraction algorithm. The number of and where to place the key frames are determined by the Perceived Motion Energy (PME) feature of a shot. The motion pattern of a typical scene is composed of a motion acceleration process and a following deceleration process and this pattern is repeated in video sequence. A triangle model is developed to describe the motion pattern and
