Video Copy Detection System Applying to IPTV
|
Abstract:
In recent years,the method of content based copy detection (CBCD) is increasingly attracting our attention as internet and wireless network develops quickly.Our paper presents a new fast and efficient system for video copy detection aiming at the particularity of IPTV.The system takes a laconic method to compare the similarity of video frames,clusters the shots into shot-clusters after selecting them from videos and makes up a tree of shot-clusters named K-means tree.The experiment results show that our system has a satisfying searching speed,as well as good rate of covering and precision.
