英文摘要：

With easier acquisition and storage of video data, the problem of how to utilize them effectively becomes increasingly serious. In recent years, enlightened by data mining, more and more researchers over the world show great interests in video mining, which is a new scientific research area deals with the extraction of video semantic info, implicit patterns and knowledge from video data. By using its technology, intelligent video applications would be well developed for assisting people in decision-making. This paper investigates video mining technology and analyzes the studying progress. The concepts, implementations and applications of video mining are summarized and discussed in detail. The challenges in the studying of this field are also put forward.
