NHK STRL at TRECVID 2009: Surveillance Event Detection and High-Level Feature Extraction

NHK Science and Technology Research Laboratories participated in two tasks at TRECVID 2009: surveillance event detection task and high level feature extraction task. For surveillance event detection tasks, we targeted four events: " P e r s o n R u n s " , " P e o p l e M e e t " , " O b j e c t P u t " , a n d "OpposingFlow". The proposed method detects human regions using HOG descriptor and S...

NHK STRL at TRECVID 2011: Surveillance Event Detection and Semantic Indexing

Laboratories participated in two tasks at TRECVID 2011: a surveillance event detection task and a semantic indexing task. Surveillance event detection is the act of detecting specific human actions from surveillance videos of crowded areas such as airports. This year, we targeted " Pointing, " " CellToEar, " " ObjectPut, " and " Embrace " actions, which our proposed system identified by using t...

MMM-TJU at TRECVID 2010

Surveillance Event Detection Semantic event detection in the huge amount of surveillance video in both retrospective and real-time styles is essential to a variety of higher-level applications in the public security. In TRECVID 2010, to overcome the limitations of the traditional human action analysis method with human detection/tracking and domain knowledge, we evaluate the general framework f...
