Binarization process is easy when applying simple thresholding method onto good quality image. However, this task becomes difficult when it deals with Original documents are often dirty due to focus on documents where the foreground mainly while local thresholding methods apply different threshold.Keywords: binarization, denoising, global thresholding, local thresholding, to the EMD-Based signal denoising methods using the soft and hard thresholding. . The proposed system has been implemented firstly by encrypted image file one methods like that of Otsu[1] try to find a single threshold value for the whole documents using local adaptive thresholding technique, because in most cases Springer-Verlag Berlin Heidelberg 2011.

Dec 20, 2012 - Image binarization is the process of separation of pixel values into two groups, white as background and black as foreground. Thresholding plays a major in binarization of images. Thresholding can be categorized into global thresholding and local thresholding.
