Applications of fuzzy morphology to contrast enhancement

Classical methods for contrast enhancement often radically alter the appearance of an image. This paper presents a method of image enhancement based on the subtext of image sharpening, i.e. improving the visual acuity of an image. We propose a contrast enhancement algorithm which is a blend of morphological analysis and fuzzy reasoning, which unlike established methods of sharpening such as unsharp masking, does not excessively accentuate noise.
