    Abstract
    Since the early 1990s, a new class of visual access tools (Visual Information Retrieval Interfaces) has been developed which use proximity as a spatial cue to user regarding the relationships among items in a collection. Discusses the theory underlying these tools, introduces a specific WWW application using the technology (InterFind), and indicates the potential of the tool for visual access to images as well as text documents. Suggests that applications incorporating this technology should be introduced to users presently, since widespread commercial introduction of products incorporating these techniques is likely to occur within the next 5 years

    Abstract
    The use of primitive content features of images for classification and retrieval has matured over the past decade. However, human beings often prefer to locate images using words. This article proposes a number of methods to utilize image primitives to support term assignment for image classification. Further, the authors propose to release code for image analysis in a common tool set for other researchers to use. Of particular interest to the authors is the expansion of work by researchers in image indexing to include image content based feature extraction capabilities in their work

    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
