چکیده

In 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. Figure 1 The overall approach for multimedia event detection.

Event detection: BJTU-SED at Trecvid 2011

In trecvid 2011, our team takes part in 2 event detection competition including pointing and cell to ear. We build two systems to recognize these events separately. For pointing, we extract texture and silhouette to recognize this action. And for cell to ear, we use orientation of optical flow and SVM classifier to finish this work.

In this paper, we describe BUPT-MCPRL systems for TRECVID 2011. Our team participated in five tasks: semantic indexing, known-item search, instance search content-based copy detection and surveillance event detection. A brief introduction is shown as follows: In this year, we proposed two different methods: one based on text and another is bio-inspired method. All 2 runs we submitted are descri...

ARTEMIS-UBIMEDIA at TRECVid 2011: Instance Search

This paper describes the approach proposed by ARTEMISUBIMEDIA team at TRECVID 2011, Instance Search (INS) task. The method is based on a semi-global image representation relying on an over-segmentation of the keyframes. An aggregation mechanism was then applied in order to group a set of sub-regions into an object similar to the query, under a global similarity criterion.
