Abstract

This study investigates the information representation power of different modalities in the video data in order to collect empirical evidence for video surrogate creation and thus better support effective video browsing and information retrieval. Three types of video surrogates - keyframe, keyword/phrase, and combination of the two were created and compared under two user tasks-verbal comprehension and visual gisting in user performance and preference. Results and discussions follow
