A novel CBCD scheme based on local features category
WISM'12 Proceedings of the 2012 international conference on Web Information Systems and Mining(2012)
摘要
Global and local features have been applied extensively to improve the performance of Content-Based Copy Detection (CBCD) systems. A novel CBCD scheme which uses global features to category local features is proposed in this paper, containing frame prerecession, database establishment and copy detection. The scheme aims to reach a fast speed and a high accuracy. A proper combination of global and local features in our scheme breeds higher efficiency and accuracy than taking use of any single feature alone. Experimental results indicate that the scheme achieves a rapid scene index and an accuracy frame-frame match.
