Design and evaluation of algorithms for image retrieval by spatial similarity
Venkat N. Gudivada, Vijay V. Raghavan
Pages: 115-144
DOI: 10.1145/201040.201041
Similarity-based retrieval of images is an important task in many image database applications. A major class of users' requests requires retrieving those images in the database that are spatially similar to the query image. We propose an...

Feedback techniques for continuity and synchronization in multimedia information retrieval
Srihari Sampathkumar, Srinivas Ramanathan, P. Venkat Rangan
Pages: 145-176
DOI: 10.1145/201040.201044
Future advances in storage and networking technologies will make it feasible to build multimedia on-demand information servers capable of providing services similar to those of a neighborhood videotape rental store over metropolitan area...

Experiments with Oval: a radically tailorable tool for cooperative work
Kum-Yew Lai, Thomas W. Malone, Christopher Fry
Pages: 177-205
DOI: 10.1145/201040.201047
This article describes a series of tests of the generality of a “radically tailorable” tool for cooperative work. Users of this system can create applications by combining and modifying four kinds of building blocks: objects,...

Exceptions and exception handling in computerized information processes
Diane M. Strong, Steven M. Miller
Pages: 206-233
DOI: 10.1145/201040.201049
Exceptions, situations that cannot be correctly processed by computer systems, occur frequently in computer-based information processes. Five perspectives on exceptions provide insights into why exceptions occur and how they might be eliminated...
