This paper proposes a method for detecting shot boundary including gradual transition based on multiple features. The proposed method enables precise, high-speed detection by omitting the processing of frames that are clearly not shot boundaries, and by analyzing various features only for the parts of the video that are likely to contain shot boundaries. An evaluation on TRECVID 2007, which is an international competition and evaluation project on video retrieval and indexing, resulted in a recall rate of 90.4％ and a precision rate of 92.8％ on average. About 425 minutes of test data was processed in 3 minutes 28 seconds (excluding the MPEG1 decoding time), 1/123 of the real time.
