Özet

In this paper we describe our participation in the interactive surveillance event detection task at TRECVid 2012. The system we developed was comprised of individual classifiers brought together behind a simple video search interface that enabled users to select relevant segments based on down sampled animated gifs. Two types of user - 'experts' and 'end users' - performed the evaluations. Due to time constraints we focussed on three events - ObjectPut, PersonRuns and Pointing - and two of the five available cameras (1 and 3). Results from the interactive runs as well as discussion of the performance of the underlying retrospective classifiers are presented.
