OCR of Nastaleeq script has gained a lot of importance during recent past owing to the requirements of preserving historic manuscripts and making such manuscripts searchable besides other applications of OCR. Nastaleeq, being a complex script, has largely remained untouched for automation till now. Whatever little work has been done so far, it has proved insufficient to fulfil the needs. Developing OCR for Urdu script based languages becomes even more complex than other languages like Latin and Chinese due to complexities of Urdu scripts, i.e. cursive nature of writing Urdu, context sensitive shapes, overlapping between ligatures, use of joiners, formation of ligatures within the words and space between the ligatures. Moreover, this paper analyses understanding of Urdu language, characteristics of Nastaleeq script and the complexities involved in developing the Urdu OCR.
