Peking University. Beijing. Dec 22, 2009: The team led by Associate Prof. Peng Yuxin at the Institute of Computer Science and Technology, PKU (PKU-ICST), on multimedia information processing,  made great success in TRECVID. Among all four test categories of High Level Feature Extraction (HLFE), the team was awarded three first prizes and one second prize, in the two test categories, ‘search’, it won a first prize and a second prize.

TRECVID is the annual international top evaluation meeting in the field of video retrieval, organized by the National Institute of Standards and Technology (USA) and held annually since 2001. This year TRECVID covered four evaluation tasks: HLFE, search, content-based copy detection, and surveillance event detection. HLFE focuses on how to make computers automatically identify the semantic concepts in the video images like a man, while search studies how to search semantic-relevant videos given search requirements. Both are key technologies in solving the problem of semantic gap and have been a major challenge in the field of multimedia field.

Most universities, institutes and corporate research centers involved in relevant studies are participators in TRECVID, which prides itself of large data collection, wide coverage and global participation.
