2006 TREC Video Retrieval Evaluation  
In this paper, we describe our experiments in high-level features extraction and interactive topic search tasks of TRECVID 2006. We designed a unified high-level features extraction framework for the 39 high-level features. Various low-level visual features were extracted from the key-frames of the shots. Then the SVM classifiers were trained fore. The final classification results were produced by fusing and combining these classifiers. The experiment results show that the combined classifiers

In topic search task, we improved our PEGASUS news video retrieval system, which has friendly user interface, fast indexing and various relevance feedback mechanisms. Based on the evaluation results, this year's topic search results are better compared to last year.
