| Abstract: | In this paper, some typical abrupt change detection algorithms are introduced, and then an improved algorithm for detecting shot abrupt change is proposed, which combines pixel-based method and histogram-based method, so the false detection problem of pixel-based method and the missed detection problem of histogram-based method can be avoided effectively. Our experiments show that this method provides good result. At the same time a method for flashlight detection is proposed to avoid the false detection problem because of certain flashlight. |
