Overview of Optical Character Recognition (OCR) Technology and Techniques

摘要

This report presents the results of a survey of 1978 Optical Character Recognition (OCR) technology conducted by NORDA Code 302, the Mapping, Charting, and Geodesy Development Group. The Systems Engineering Branch, Engineering and Science Services Laboratory (ESSL), National Space Technology Laboratories was contracted for a major portion of this effort. The survey was required by the Defense Mapping Agency (DMA) funded OCR system development efforts within NORDA. Three principal areas of OCR technology development were reviewed: Government applications of OCR. Commercial OCR products. Software and basic research. This document also contains an extensive bibliography and discussion of selected papers. (Author)
