Exploratory Video Search by Augmented Playback

Gargi, Ullas; Banerjee, Somnath

External - Copyright Consideration

Keyword(s): video browsing; video search

Abstract: Exploratory search or browsing interfaces to digital video have traditionally followed the approach of navigating a pre-computed index based on content analysis, annotational metadata, or both. Examples include video storyboards, video skims, etc. We propose a new paradigm for exploratory video search based on augmenting video playback with metadata channels and flexible play back modes. Our method uses content analysis as well as optional user input to determine higher semantic importance segments of video and varies the playback rate of video accordingly. A past and future keyframe buffer as well as a fluid user control interface allow the user to keep track of the video while still moving through it at high speed. Preliminary results in this ongoing project are presented.
