    图书Optical and Digital Pattern Recognition (Proceedings of Spie--the International Society for Optical Engineering, Vol ) 介绍、书评、论坛及推荐. 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.

    Optical processing over the past 10 years has made significant advances in implementing a great number of digital pattern recognition algorithms. Especially important are optical implementations of digital algorithms that involve global operations on 2-D patterns. Such applications of optical processing will significantly speed up the response time of the pattern recognition systems while. Pattern Recognition Using Neural Networks, Carl G. Looney Fifty True Mysteries of the Sea, John Canning Acousto-Optic Signal Processing - Theory and Implementation, Second Edition, Berg.

    To the digital age The first prominent piece of OCR software was invented by Ray Kurzweil in as the software allowed for recog-nition for any font [5]. This software used a more developed use of the matrix method (pattern matching). Essentially, this would compare bitmaps of the template character with.   Both methods employ ANN for pattern recognition in conjunction with features extraction approaches and digital signal processing. In the first method, asynchronous amplitude sampling is the features extraction method. For high-speed optical communications, new approach using ANN trained by the features of linear optical sampling is implemented.

This book provides a comprehensive review of optical pattern recognition, covering theoretical aspects as well as details of practical implementations and signal processing techniques.

The first 5/5(1). This study provides a basic understanding of the fundamentals of optical pattern recognition systems.

An emphasis on the capabilities and limitations of such systems is presented. His research interests include optical information processing, image encryption, watermarking, digital holography, interferometry, correlation based optical pattern recognition, and fractional Fourier transform-based signal processing.

He is a senior member of OSA, SPIE and life fellow of Optical. To recognize digital streams of digital data, all-optical and passive techniques able to discriminate optical bit words in real time are presented. Discrimination capability of different correlators, both in free space architectures and in delay lines structures, is theoretically and experimentally analyzed.

Experimental performances in word recognition are shown in the case of a volume. Integration of other pattern recognition data which supplements the OPS analysis leads to an increased pattern classification potential.

The optical/ digital system discussed integrates a photo diode array detector in the image domain with the OPS system. An optical-digital system for the pattern recognition of coal-workers' pneumoconiosis is described. The system consists of a coherent-optical configuration to generate the Fourier irradiance of the radiographic image and a digital computer to process the data.

The interface is a TV camera. Optical pattern recognition is one of the most powerful operations possible on a coherent or an incoherent optical system. Matching two images and learning the likelihood of two pattern-matched objects are one of the main roles in various schemes of pattern recognition operations [1].

Optical character recognition or optical character reader (OCR) is the electronic or mechanical conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene-photo (for example the text on signs and billboards in a landscape photo) or from subtitle text superimposed on an image (for example: from a.

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.

Optical power spectral (OPS) analysis has demonstrated significant advantages for rapidly classifying simple patterns from aerial transparencies.

However, as the pattern sets become larger and more complicated, the required software is more complex, the equipment requirements more demanding, and the processing time increases.

Additionally, potential ambiguity of the OPS data due to loss of. Optical processing, such as pattern recognition and encryption, by digital holography also offers new capabilities [ 28 ]. Basic principles of diffraction and general holography are outlined in Sec.
