Paper: Carnegie Mellon University Traditional Informedia Digital Video Retrieval System Christel, M., Proc. International Conference on Image and Video Retrieval (CIVR'07),Amsterdam, The Netherlands, p. 647, July 9-11, 2007 Abstract:   The Carnegie Mellon University Informedia group has enjoyed consistent success with TRECVID interactive search using traditional storyboard interfaces for shot-based retrieval. For TRECVID 2006 the output of automatic search was included for the first time with storyboards, as an option for an interactive user. This access mechanism, query-by-best-of-topic, complements other access strategies, namely query-by-text (dominated by closed captioned text), query-by-image (primarily color-based syntactic lookup), and query-by-concept (using concept classifiers trained through machine learning techniques). The interface is tuned to support efficient performance required for TRECVID interactive search tasks where a maximum of 15 minutes can be spent per task. This 4-strategy Informedia interface scored significantly better than all other TRECVID 2006 interactive search systems. Interface attributes will be demonstrated in shot-based retrieval from news corpora. Close
