Functions ¶

func Sharpen ¶

func Sharpen(in image.Image, radius int, sigma float64) image.Image

Sharpen takes an image and sharpens it by, essentially, unblurring it. It is currently extremely slow, so you are probably better off sticking to UnsharpMask.

func UnsharpMask ¶

func UnsharpMask(in image.Image, radius int, sigma, amount, threshold float64) image.Image

UnsharpMask sharpens the given Image using the unsharp mask technique. Basically the image is blurred, then subtracted from the original for differences above the threshold value.
