This page answers a few common questions about the following plugins writing during my Master Thesis :
These plugins are under the GPL license version 2.

General

Could you make modification "xyz" to your plugin ?

I am not currently working or using the plugins. If you are planning to write a research article that would need some modifications please contact me.

Where can I obtain the source code of your plugins ?

The source code is distributed with the archive (which in ZIP format) under the GPL license version 2.

Where can I find a tutorial for ImageJ ?

Your plugin "..." does not work !

I'm very sorry you have encountered problems with the plugin. I have used them for my work and they seemed to give results consistent with referenced articles. However some mistakes/bugs could well have been left out. I would be quite happy to integrate your contribution to the plugin and make the new version available.
 

Otsu thresholding

Where can I find the article "A threshold selection method from gray level histograms", 1979 ?

It's often difficult to find old articles but a lot of authors who publish work based on them write a reminder of the techniques used which is the case for the Otsu thresholding in this article :

@article{DBLP:journals/jise/LiaoCC01,
author = {Ping-Sung Liao and
Tse-Sheng Chen and
Pau-Choo Chung},
title = {A Fast Algorithm for Multilevel Thresholding.},
journal = {J. Inf. Sci. Eng.},
volume = {17},
number = {5},
year = {2001},
pages = {713-727},
ee = {http://www.iis.sinica.edu.tw/JISE/2001/200109_01.html},
bibsource = {DBLP, http://dblp.uni-trier.de}
}

Anisotropic diffusion

What algorithm of the Anisotropic Diffusion did you implement? do you use the version with a 1/|grad| or exp(-|grad|) ?

By default the method used is 'exp' and the option 'Big region method' refers to the equation '1/(1+(DI/K)2)' (1/|grad|) described in the article (p633).
