A Survey on Offline Recognition of Handwritten Devanagari Script

Devanagari Script is mostly useful in India for writing number of official forms and documents, especially in the banking applications for writing amount in words on the cheque. The Offline recognition of handwritten Devanagari script has great application in automatic processing of handwritten bank cheques images, documentation of various official documents as well as digitization of government and non government documents. In this paper it has been tried to achieve automatic recognition of handwritten Devanagari Script by using various algorithms.
