A Detailed Study and Analysis of OCR Research in South Indian Scripts

This paper provides an overview of the OCR (optical character recognition) research in South Indian languages. OCR reading technology is benefited by the evolution of high-powered desktop computing allowing for the development of more powerful recognition software that can read a variety of common printed fonts and handwritten texts. But still it remains a highly challenging task to implement an OCR that works under all possible conditions and gives highly accurate results. There were a lot of ongoing works in Indian scripts. The aim of this paper is to provide an introduction for the researchers in this field. Since we have only limited facilities for South Indian languages, the area is still promising and indeed it is the need of the society. We have tried to describe the specialties of the scripts, techniques employed in, recognition methods and the result comparison of different OCR methods developed for South Indian languages in this paper.
