Optical Character Recognition (OCR) is a very old and of great interest in pattern recognition field. In this paper we introduce a very powerful approach to recognize Persian text. We have used morphological operators, especially Hit\/Miss operator to descript each sub-word and by using a template matching approach we have tried to classify generated description. We used just one font in two different sizes to verify our approach. We achieved a very good rate, up to 99.9%.<\/p>\r\n","references":"[1] Badr Al-Badr and Saberi A.Mahmoud, \"Survey and bibliograghy of Arabic optical text recognition\",Elsevier Signal Processing,1995, pp.49-77.\r\n[2] seera, J.,Image Analysis and Mathematical Morphology\", Acrdemic\r\nPress, NewYork, 1982\r\n[3] J.W.
