2005 TREC Video Retrieval Evaluation  
Our main focus for this year was on setting up a flexible retrieval environment rather than on evaluating novel video retrieval approaches. In this structured abstract the submitted runs are briefly described. High-level feature extraction We experimented with feature detectors based on visual information only, and compared Weibullbased and GMM-based detectors. • LL-HF-WB-VisOnly Region-based Weibull models, visual only • LL-HF-WBNWC-VisOnly Extended region-based Weibull models, visual only •

Some models are good for one topic other for the next. Future research has to show whether a combined approach is useful.
