Partitioning a video sequence into shots or detecting shot change is one of the key techniques in video indexing. This article summarizes some commonly used methods for partitioning video into shots which are pixel level-based methods, histogram methods, X2 histogram methods, X2 block histogram methods, edge silhouttee rat of changing mathods, and detailedly introduces various algorithms of frames difference value calculation, and introduces the advantages and disadvantages of them, and the results of these algorithms are compared through the experiments, the advantages and disadvantages of Five algorithm at the experiments are very well reflected.
