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.
