I've seen an very interessting video (http://meetthegimp.org/episode-127-octave-sharpening/) about the so called "Octave Sharpening" I've never heard. So I started searching for some information about it and found also 2 other sharpening methods (http://www.varis.com/StepByStep/sharpen/Sharpen.html).
The PDF tutorial (second link) shows the function with Photoshop so I implemented the scripts for gimp and wondered how effectfull they are.
Here is version 1.0. Any feedback welcome...
Install:
Copy the files to your Gimp script user folder:
Linux: /home/[USER]/.gimp-2.6/scripts/
Windows: C:\Documents and Settings\[USER]\.gimp-2.6\scripts\
Use:
The scripts can than be found in Gimp under:
Filters --> Enhanced --> ... Sharpening

Hi! Split sharpening only
Hi!
Split sharpening only creates two unchanged copies of the background if you don't change the radius/amount options. Wouldn't it be better with sliders?
Error in octave script
Hi-
See http://forum.meetthegimp.org/index.php/topic,756.0.html where a scheme script and a python script were provided to do octave sharpening. It looks like your script has the same bug identified in the forum post there with the new-from-visible call.
