India is a multi-lingual country. A significantly large number of scripts are used to represent these languages. A desire of vision researchers is to develop an integrated Optical Character Recognition (OCR) system which will be able to process all such scripts. Such a development, if objectified, will not only enable faster flow of information across the country, but also have a profound impact on its scientific and economical development. Courageous endeavours have been successfully made towords the development of systems capable of recognizing machine-printed, or hand-written characters and/ or numerals. However, most Indian scripts do not have an nitrated OCR system. Furtherer, the development of a unified system which is capable of processing all Indian scripts is still a dream. The article presents a survey of the current literature on the development of OCR’s in Indian scripts. Reviewing the basics of of and the motivation towards the development of OCR system, the article analyzes the various methodologies employed in general purpose pattern recognition systems. A critical analysis of the work towards OCR systems in Indian Languages, with pointers towards possible future work is also presented.
