Contrast Enhancement Based on a Morphological Rational Multiscale Algorithm

Abstract. Contrast enhancement is an important task in image processing and it is commonly used as a preprocessing step in order to improve the results for other tasks such as segmentation. However, not only do some methods for contrast improvement have good performance working on low contrast regio...
