Proc. Ninth Int. Conference on Document Analysis and Recognition (ICDAR), IEEE Computer Society (2007), pp. 629-633

Abstract

The Tesseract OCR engine, as was the HP Research Prototype in the UNLV Fourth Annual Test of OCR Accuracy[1], is described in a comprehensive overview. Emphasis is placed on aspects that are novel or at least unusual in an OCR engine, including in particular the line finding, features/classification methods, and the adaptive classifier.
