Image enhancement via adaptive unsharp masking
Andrea Polesel, Giovanni Ramponi, V.J. Mathews · IEEE Transactions on Image Processing · 2000
This paper presents a new method for unsharp masking for contrast enhancement of images. The approach employs an adaptive filter that controls the contribution of the sharpening path in such a way that contrast enhancement occurs in high detail areas and little or no image sharpening occurs in smooth areas.
