Script-Fu -> Warp Sharp






This is an adjustable script
which gives an image a slightly sculpted or painterly look...
eliminating some detail "noise"

This implements a method to sharpen images described by Joern Loviscach in the german computer magazine c't, 22/1999.

Basically it "squeezes" unsharp edges. This method is a simplified Version of an algorithm by Nur Arad and Craig Gotsman:
"Enhancement by Image-Dependent Warping",
IEEE Transactions on Image Processing, 1999, Vol. 8, No. 8, S. 1063
