An HMM-based Farsi OCR

OCR (Optical Character Recognition) is the digital encoding of printed and handwritten characters from an image file created through a scanner or other optical imaging devices. In other words, OCR is a software program that converts image-texts into computerized or digital text (figure 1) . While OCR has been extensively used as the basic application of different learning methods in machine learning literature for a few decades now, few researches have been done specifically for the language Farsi which is mainly due to cursive nature of Farsi scripts.
