Optical personality reputation (OCR) is the main sought after and winning instance of development attractiveness up to now. there are literally thousands of examine papers and dozens of OCR items. Optical CharacterRcognition: An Illustrated advisor to the Frontier bargains a viewpoint at the functionality of present OCR structures by means of illustrating and explaining real OCR mistakes. the images and research offer perception into the strengths and weaknesses of present OCR platforms, and a street map to destiny development.
Optical personality popularity: An Illustrated consultant to the Frontier will pique the curiosity of clients and builders of OCR items and laptop scanners, in addition to lecturers and scholars of trend acceptance, man made intelligence, and data retrieval. the 1st bankruptcy compares the nature popularity skills of people and desktops. the subsequent 4 chapters current 280 illustrated examples of popularity mistakes, in a taxonomy including Imaging Defects, comparable Symbols, Punctuation, and Typography. those examples have been drawn from large-scale exams carried out by means of the authors. the ultimate bankruptcy discusses attainable methods for bettering the accuracy of modern-day platforms, and is by means of an annotated bibliography.
Optical personality attractiveness: An Illustrated consultant to the Frontier is appropriate as a secondary textual content for a graduate point path on trend popularity, man made intelligence, and knowledge retrieval, and as a reference for researchers and practitioners in industry.
