Image Enhancement of Historical Image Using Image Enhancement Technique

Image enhancement technique is one of the very challenging issues in the image processing technique. The main motive of the image enhancement process is to work on an image or picture so that the result should be more applicable than original. Historical docs are very important origin of information, but it commonly suffers from the problem of getting degrade. The main aim is to keep all of these documents secure and alive. The purpose is to enhance the quality and visualization of the historical image. In this paper, we have used improved adaptive histogram equalization of the contrast of the image, and we have analyzed the result.
