Enhancement of document images using multiresolution and fuzzy logic techniques
1999
IEEE Signal Processing Letters
This letter presents a method for enhancing document images based on the multiresolution decomposition and fuzzy logic approach. The document image to be enhanced is obtained from a scanner and is a blurred binary image that is corrupted by additive noise. This type of image occurs in many situations when documents such as checks and credit card receipts become noisy and loww-contrast images after scanning, thereby reducing its quality. Our task is to improve the readability of such images by
