Raster Image - Unsharp Mask

The Unsharp Mask operation is an operation plug-in, which modifies raster images by emphasizing edges.

Unsharp mask works by subtracting a blurred version of the image from the original image. The Radius parameter controls the blurring radius. The Amount parameter determines a factor for subtracting. Threshold is the minimum difference for the sharpening to take effect.
