Hello,
It depends on your use case. You may consider using the Sharpen
function. It uses the unsharp mask algorithm internally, but it doesn't support the threshold
and amount
parameters.
If you need more control on the parameters, you may use the Blur
function to create a blurred copy of your image and then calculate a value for each pixel according to the formula Sharpened = Original + ( Original - Blurred ) * Amount
.
The wikipedia article: https://en.wikipedia.org/wiki/Unsharp_masking
See also the github.com/disintegration/gift
package for more complete implementation of the unsharp mask filter: https://godoc.org/github.com/disintegration/gift#UnsharpMask
