A filtering tool to support interactive search in Internet video archives.

We present a novel interface for large-scale video archives that uses content-based filtering of search results. The interface has been used for the Interactive Known-Item Search (Interactive KIS) task of TRECVID 2012 and achieved good search performance. We found that for KIS tasks content-based filtering as used in our interface is convenient and able to successfully narrow down interactive search for many of the TRECVID KIS queries used in 2012. We demonstrate the usefulness of our approach, where three types of content-based filters (color detection, audio classification and video concept detection) can be combined.
