Book Description
The survey of automatic character recognition techniques covered in this report has been conducted over a period of several years by teams of National Bureau of Standards personnel including, at various times, S. N. Alexander [and 10 others]. Much of the information herein was obtained through the courtesy of personnel of other organizations, especially those which are engaged in the design and development of reader devices.

Book Description
The book offers a comprehensive survey of soft-computing models for optical character recognition systems. The various techniques, including fuzzy and rough sets, artificial neural networks and genetic algorithms, are tested using real texts written in different languages, such as English, French, German, Latin, Hindi and Gujrati, which have been extracted by publicly available datasets. The simulation studies, which are reported in details here, show that soft-computing based modeling of OCR systems performs consistently better than traditional models. Mainly intended as state-of-the-art survey for postgraduates and researchers in pattern recognition, optical character recognition and soft computing, this book will be useful for professionals in computer vision and image processing alike, dealing with different issues related to optical character recognition.

Book Description
Excerpt from Automatic Character Recognition: A State-of-the-Art Report Such techniques promise major advantages in a wide variety of data processing and data handling situations, specifically including thos-e of mechanized information selection systems and mechanized translation. These potential advantages include reductions in manpower requirements as well as reductions of errors and inaccuracies found in manual data transcription operations. This report incorporates the results of a fact-finding survey of automatic character reading techniques which was conducted by the National Bureau of Standards for the Rome Air Development Center in the period 1956-1957. The earlier survey has been extended and supplemented by study of the available literature, by continuing inspections of character reader devices, and by periodic discussions with research and development personnel interested in automatic character recognitiontechniques. The purpose of this report is therefore to review current developments in the-field of character recognition, with emphasis upon actual devices designed to identify printed or typed information.

Book Description
Optical character recognition (OCR) is the most prominent and successful example of pattern recognition to date. There are thousands of research papers and dozens of OCR products. Optical Character Rcognition: An Illustrated Guide to the Frontier offers a perspective on the performance of current OCR systems by illustrating and explaining actual OCR errors. The pictures and analysis provide insight into the strengths and weaknesses of current OCR systems, and a road map to future progress. Optical Character Recognition: An Illustrated Guide to the Frontier will pique the interest of users and developers of OCR products and desktop scanners, as well as teachers and students of pattern recognition, artificial intelligence, and information retrieval. The first chapter compares the character recognition abilities of humans and computers. The next four chapters present 280 illustrated examples of recognition errors, in a taxonomy consisting of Imaging Defects, Similar Symbols, Punctuation, and Typography. These examples were drawn from large-scale tests conducted by the authors. The final chapter discusses possible approaches for improving the accuracy of today's systems, and is followed by an annotated bibliography. Optical Character Recognition: An Illustrated Guide to the Frontier is suitable as a secondary text for a graduate level course on pattern recognition, artificial intelligence, and information retrieval, and as a reference for researchers and practitioners in industry.
