Recent research in video retrieval has focused on automated, highlevel feature indexing on shots or frames. One important application of such indexing is to support precise video retrieval. We report… (More)
This paper describes the details of our systems for feature extraction and search tasks of TRECVID-2004. For feature extraction, we emphasize the use of visual auto-concept annotation technique, with… (More)
When querying a news video archive, the users are interested in retrieving precise answers in the form of a summary that best answers the query. However, current video retrieval systems, including… (More)
We present a higher-level visual representation, visual synset, for object categorization. The visual synset improves the traditional bag of words representation with better discrimination and… (More)
We participated in the high-level feature extraction and search task for TRECVID 2005. For the high-level feature extraction task, we make use of the available collaborative annotation results for… (More)
NUS and IR joint participated in the high-level feature extraction and automated search task for TRECVID 2006. In both task, we only make use of the standard TRECVID available annotation results. For… (More)
We present a probabilistic ranking-driven classifier for the detection of video semantic concept, such as airplane, building, etc. Most existing concept detection systems utilize Support Vector… (More)
Existing video research incorporates the use of relevance feedback based on user-dependent interpretations to improve the retrieval results. In this paper, we segregate the process of relevance… (More)
In this paper, we highlight the use of multimedia technology in generating intrinsic summaries of tourism related information. The system utilizes an automated process to gather, filter and classify… (More)
This paper describes the details of our systems for our automated and interactive search in TRECVID 2007. The shift from news video to documentary video this year has prompted a series of changes in… (More)
