Industrial OCR approaches: architecture, algorithms, and adaptation techniques
István Marosi · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2007
Optical Character Recognition is much more than character classification. An industrial OCR application combines algorithms studied in detail by different researchers in the area of image processing, pattern recognition, machine learning, language analysis, document understanding, data mining, and other, artificial intelligence domains. There is no single perfect algorithm for any of the OCR problems, so modern systems try to adapt themselves to the actual features of the image or document to be recognized. This paper describes the architecture of a modern OCR system with an emphasis on this adaptation process.
