"Hierarchical Video Annotation"

Abstract: Over the past few years there has been an incredible growth in collections of video data arising from diverse sources ranging from cell phones to sophisticated surveillance platforms. Most of this video data is relatively difficult to access due to the challenges in describing the video data so that it can be retrieved or understood without viewing. This talk describes some of the recent work that has been done at OSC on video annotation. Video annotation is the automatic or semi-automatic addition of content-derived information that can be extracted from video sequences in order to allow video to be identified, categorized, or differentiated. I will describe a collection of techniques we've developed that allow certain restricted forms of video to be described in terms of automatically generated labels and how those labels can be analyzed and grouped semantically.
