    "TRECVid & future of video search"
    Wessel Kraaij and Alan Smeaton

    Abstract

    TRECVid is the leading annual benchmark conference on content based video indexing & retrieval techniques. In seven years, TRECVid has evaluated various component tasks and attained a participation of 40+ research groups from North America, Europe, Asia and Australia. TRECVid stimulates innovative research on video access by providing a standardized testbed allowing comparison of approaches. An important element determining the success of TRECVid is the fact that it is driven by the research community itself.

    Some of the component tasks that have been studied can be considered as solved (such as shot boundary detection), others such as generic concept indexing are still way behind the accuracy of textual indexing techniques that internet users expect. In this talk we will contrast state of the art video indexing and retrieval techniques with some of the existing video search services that are deployed. An example is the role and importance of manual annotation. Concept indexing techniques typically depend on the availability and reliability of manually annotated keyframes. Existing video search applications also rely on manual content descriptions, but these usually apply to the full clip. We will also assess the potential impact of TRECVid on end user solutions for video search and in what way the current video search solutions influence new tasks for TRECVid.
