摘要：Binarization is an important preprocessing step in several document image processing tasks.Binarization of historical document with poor contrast, strong noise, and non-uniform illumination is a challengingproblem. A new binarization algorithm has been developed to address this problem. In this approach, we describe anew method which does utilize statistical properties of the intensity histogram of a gray-scale image to determine athreshold. It uses low pass Weiner filter method as a preprocessing step to enhance the image by deblurring the image.It uses Median Filter method as a postprocessing step to reduce noise in the image. Our result shows that this newbinarization method produce high quality binary image for historical document than any other global methods such asOtsu‟s method.
