AbstractIn this paper, we present results from the experimental evaluation for the TRECVID 2011 MED11 (Multimedia Event Detection) task as a part of Team SRI-Sarnoff’s AURORA system being developed under the IARPA ALADDIN Program. Our approach employs two classes of content descriptions for describing videos depicting diverse events: (1) Low level features and their aggregates, and (2) Semantic concepts that capture scenes, objects and atomic actions that are local in space-time. In this presentation we summarize our system design and the content descriptions used. We also present four MED11 experiments that we submitted, discuss the results and lessons learned.
