Recently, local interest points (also known as key points) are shown to be useful for content based video copy detection. The state-of-art local feature based methods usually build on the bag-of-visual-words model and utilize the inverted index to accelerate search process. In this paper, we offer a detailed description of a novel CBCD system. Compared with the existing local feature based approaches, there are two major differences. First, besides the descriptors, the dominant orientations of local features are also quantized to build the hierarchical inverted index. Second, feature similarity constraints are used to refine the matching of visual words. Experiments performed on a reference video dataset of 50 hours show that our system can deal with 9 types of common video transformations, and due to the hierarchical indexing and feature similarity constraints, the computational costs are reduced as well.
