A set of morphological operators for GIMP:
- erosion and dilation
- opening and closing
- boundary extraction and gradient
- thickening and thinning
- white and black top-hat
The plugin is tested to work on GIMP starting from 2.6 version.http://www.alessandrofrancesconi.it/projects/morphop/
This script sharpens an image with the built-in GIMP plugins erode and dilate.
These two plugins infiltrate the image with the lowest/highest pixel of the closer environment, but never higher or lower.http://docs.gimp.org/en/plug-in-dilate.htmlhttp://docs.gimp.org/en/plug-in-erode.html
This means, they can be used to sharpen an image w/out halos.
