A method and a system for generating summarized video |
摘要 |
An algorithm for video summarization is described. The algorithm combines photometric and motion information. According to the algorithm, the correspondence between feature points is used to detect shot boundaries and to select key frames. Thus, the rate of feature points, which are lost or initiated, is used as an indication if a shot transition occurred or not. Key frames are selected as frames where the activity change is low. |
