In this paper, a new scheme is proposed to extract the global motion model from general video sequence. Since global camera motion often conveys the semantic meaning of the video’s content, these global model parameters are used as features for video retrieval. Experimental results show our scheme is quite effective in locating video segments with similar motion content in football game sequences. Introduction: In general video sequences, the movement of the camera always follows the place where the important activity goes on. This means the camera motion contains cues of the semantic meaning of the video, especially in some constrained domain. One good example of this is the football game. In football game video, the camera’s movement is often focusing on the trajectory of the football and the position of the players. This information could be used as the feature for the retrieval of the football sequence. In football games, color an
