Abstract

Today, more and more video information can be accessed through internet, satellite, etc.. Retrieving specific video information from large-scale video database has become an important and challenging research topic in the area of multimedia information retrieval. Generally, video retrieval can be categorized by the retrieval of video shot and retrieval of video clip. Up to now, few approaches can support both shot retrieval and clip retrieval efficiently. In this paper, we introduce a new high-dimensional index structure OVA-File, which is a variant of VA-File. In OVA-File, the approximations close to each other in data space are stored in close positions of the approximation file. The benefit is that only a part of approximations near the query vector need to be visited to get the approximate query result. Then, both shot query algorithm and video clip query algorithm are proposed to support video information retrieval efficiently. The experimental results showed that the queries based on OVA-File were much faster than that based on VA-File with small loss of result quality.
