AN IMPROVED METHOD TO REMOVE NOISE FROM DEGRADED DEVANAGARI SCRIPT SCAN DOCUMENT

In this paper a number of classical methodologies together with the recent works are considered for comparison and study of the concept of segmentation for both document and graphic images. we propose segmentation method for noisy document. The segmentation method is proposed for Devnagari document by considering the structure of Devnagari script .We have also consider the irregularities of Devnagari writing style , Yuktaksha and numbers. We are not removing shirorekha. It separates the image text documents into lines, words and characters. We are getting 100% accuracy at line and word level but at character level it depend on the type of character, whether it is single ,Yuktakshar or triakshar.
