Abstract : Document images are often obtained by digitizing the paper documents like books or manuscripts. Due to degradation of paper quality, aging spreading of ink etc their appearance may get poor. Document may undergo termite bite due to aging and will get severely degraded .This work tries to find some solutions to increase the recognition rate of degraded characters after applying a best preprocessing technique for removing the noise due to termite bite. Main degradation for a degraded document are due to non-rectilinear camera positioning, blur, bad illumination, non-uniform backgrounds, non-flat paper surface, spreading of ink, document aging,extraneous marks, broken characters. There are different systems which are able to deal with degradations which occur due to these type of degradations. Restoration is highly useful in a variety of fields such as document recognition, historic document analysis etc. In this paper ,we propose a method to remove the noise due to termite bite . The work has the ability to deal with larger patch sizes and allows to deal with severe degradations.
