Title

¬A method for automatically abstracting visual documents

Abstract

Visual documents - motion sequences on film, videotape, and digital recordings - constitute a major source of information for the Space Agency, as well as other government and private sector entities. This article describes a method for automatically selecting key frames from visual documents. These frames may in turn be used to represent the total image sequence of visual documents in visual libraries, hypermedia systems, and training guides. The performance of the abstracting algorithm reduces 51 minutes of video sequnces to 134 frames; a reduction of information in the range of 700:1
