In addition to reviewing the characteristics of document processing systems, this paper pays considerable attention to the description of a system via a feature list approach. The purpose of this report is to present features of the systems in parallel fashion to facilitate comparison so that a potential user may have a basis for evaluation in…

This report delineates the theory and terminology of data compression. It surveys four data compression methods--null suppression, pattern substitution, statistical encoding, and telemetry compression--and relates them to a standard statistical coding problem, i.e., the noiseless coding problem. The well defined solution to that problem can serve…

Describes a program written in VS BASIC which was created for the online tabulation, summarization, and display of information on collection size for an academic library and compares its performance with that of SAS (Statistical Analysis System). Nine figures compare tables produced by the two systems, and two references are given. (RAA)

The aim of the CYCLOPS Project research is the development of techniques for allowing computers to perform visual scene analysis, pre-processing of visual imagery, and perceptual learning. Work on scene analysis and learning has previously been described. The present report deals with research on pre-processing and with further work on scene…
