History: 2001/06/19: (version 1.0.3)
2003/12/09: Renamed Filter_Rank and modified by G. Landini
Source: Filter_Rank.java Installation: Download Filter_Rank.class to the plugins folder and restart ImageJ. Description: This is a contrast-enhancing ImageJ plugin for 8 bit greyscale images. It creates a new contrast-enhanced image from the processed image. It asks for the geometric half length (halfLength) of the contrast-enhancing square. More information is available at http://www.artenum.com/en/produits/libre/ijce/ijce.html.
The contrast-enhancing algorithm was proposed by Didier Pelat (Paris Observatory http://www.obspm.fr/) and implemented by Artenum (http://www.artenum.com/).
Filter_Rank version 1.1.0 based on Contrast_Enhancer_ version 1.0.3
Modified by G. Landini G.Landini@bham.ac.uk on 23/Nov/2003:
- Changed "half-length" for "filter window size" (more intuitive)
- Added option to do (or rather "not to do") rank randomisation, so please be aware of this change in the algorithm
- Added option for (not to) rescale to 8 bit range (to keep the real rank value)
- Added option to overwrite the image data (no new image is created)
- Added capability to filter stacks and to be recordable (for macro creation)
- Moved dialog to setup()
- Added "About..."
Pending issues / bugs: When a stack is processed and "Create new image" is checked, it creates individual images rather than a new stack. As a temporary measure do run("Convert Images to Stack"); to merge result into a stack.
