The effects of image enhancement in OCR systems: a prototype
Ray R. Hashemi, David R. Owen, M.S. Smith, T. Flanigan, John R. Talburt · 2002
The accuracy of the optical character recognition (OCR) systems is highly dependent upon the quality of the image. We investigate and propose solutions to several issues that can arise in the processing of binary images of scanned, typeset text. The issues of concern are image residues from adjacent lines, character touching, boldface character recognition, and text repairing.
