Alternatively, one could employ one of the more advanced sharpening techniques (coming soon). Another complication of using an unsharp mask is that it can introduce subtle color shifts.

In recent years, the detection of USM sharpening has attracted attention from image forensics point of view. After USM sharpening, overshoot artifacts, which shape image texture, are generated along image edges. WebbMRI-based diagnosis and clinical interventions become difficult due to the vague textural information and weak morphological margins on images. A novel image sharpening algorithm named as maximum local variation-based unsharp masking (MLVUM) to address the issue of 'unsharpness' in MRI is proposed in this paper.

USM has been widely used for image sharpening because of its speed and simplicity. The key idea is to add a fraction l of an unsharp mask to the input image; this fraction is obtained by subtracting the input and its low-pass filtered image.
