%X Color histogram and pixel differences algorithms only test in a limited material. In order to research these algorithms' used areas, this paper designed and implemented three algorithms and constructed a test video set. After test, it analyzed these algorithms' performance. And it concludes that a algorithm's performance requires a trade-off between recall and precision that must be guided by the user's demand.
