DSP based Optical Character Recognition for Devnagari charaters.

Computer Engineering

Optical Character Recognition (OCR) is a research area that has attracted the interest of researchers for the past forty years. Character recognition is the mechanical or electronic conversion of scanned image of handwritten, typewritten or printed text into machine encoded text. Although the subject has been the center topic for many researchers for years, it remains one of the most challenging and exciting areas in pattern recognition. In our project, a robust DSP-based OCR is developed to recognize the Devnagari characters, display them as well as produce output in audio form. There are millions of people in India who speak Hindi and write Devnagari script. Research in Optical Character Recognition (OCR) is popular for its application potential in banks, post offices, defense organizations and library automation etc. However most of the OCR systems are available now but they were only software based. In this work, a technique for OCR System for different five fonts and sizes of printed Devnagari script which will be hardware related. The recognition rate of the proposed OCR system with the document of image of Devnagari Script has been found to be quite high.
