Having a long term experience in TRECVID activities, COST292 partners have decided to submit results for evaluation in all four system task of TRECVID 2007, namely shot boundary determination, high-level feature extraction, interactive search and rushes exploitation. This action is coordinated by Qianni Zhang from Queen Mary University of London, United Kingdom.

Shot boundary detection task is to identify the shot boundaries with their location and type (cut or gradual) in the given video clip. The submission is led by Marzia Corvaglia from university of Brescia, Italy, joined by contribution from METU, Delft University of Technology, University of London Queen Mary and LABRI.

High-level features system task is evaluating the effectiveness of detection methods for high-level semantic concepts such as "Indoor/Outdoor", "People", "Speech". The group leader is Dr. Selim Aksoy from Bilkent University. Additional contributors from UBI, QMUL, Delft, University of Zilina, NTUA, TID, University of Novi Sad.

The central system task of interactive search is led by Qianni Zhang from QMUL. Additional contributors by ITI, University of Belgrade and Zilina.

Finally, the rushes task is coordinated by Delft University of Technology contributions from LABRI, VicomTech and University of Bristol.

After the initial meeting of the COST292 technical committee in Delft, Netherlands on 1-2 March 2007, it is decided which partners will coordinate and contribute to which system task as well as that the first submission workshop of the TRECVID activity will be hosted by LABRI in Bordeaux, France on 19 March 2007. Follow-up activity is planned on 7-8 June from Santorini, Greece to conduct the search experiments and compile the search task results.

The core milestones of the TRECVID 2007 submission are as follows:

Collaborative annotation

Web site for common annotation: http://mrim.imag.fr/tvca
To do the annotations: http://mrim.imag.fr/tvca/al.html


Shot boundary detection task

High-level feature extraction task

Interactive search task

The system submitted to the search task is an interactive retrieval application combining retrieval functionalities in various modalities (i.e. visual, audio, textual) with a user interface supporting automatic and interactive search over all queries submitted.

The basic retrieval modules integrated in the developed search application are:

Rushes task
