摘要：Optical Character Recognition (OCR) is the task of recognizing the characters which are present in adigital image of text, whose domain can be machine print or handwriting. OCR is one of the most fascinating andchallenging areas of pattern recognition with various practical application potentials. The present paper proposes amethod for recognizing the Telugu Numerals from zero to nine by using the Moment Invariants. For this, the proposedmethod uses boundary based shape representation scheme. The input Telugu numeral is decomposed in to one levelHaar wavelet transformed sub bands and the Boundary Moment Invariants are measured for each of these four subbands. The experimental results show the superiority of the proposed method to recognize the Telugu numerals.
