[OSGeo-Discuss] OSGeo ISODATA implementation?

[Himanshu Singh]

Hi Nikolas,

Last year, I implemented ISODATA clustering plugin for
Opticks<http://opticks.org>.
It is available for download as an Opticks extension here: Machine Learning
Tools for Opticks<http://opticks.org/confluence/display/opticksExt/Machine+Learning+Tools+for+Opticks>.
You may take a look at it and see if it suits your need.
More information about the extension is available here:
http://himanshusingh.github.com/Machine-Learning-Tools-for-Opticks/

Source code of my ISODATA implementation is here:
ISODATA.cpp<https://github.com/himanshusingh/Machine-Learning-Tools-for-Opticks/blob/master/Code/ISODATA/ISODATA.cpp>.
It is based on:
N. Memarsadeghi, D. M. Mount, N. S. Netanyahu, and J. Le Moigne,
A Fast Implementation of the ISODATA Clustering
Algorithm<http://www.cs.umd.edu/%7Emount/Projects/ISODATA/ijcga07-isodata.pdf>
*International Journal of Computational Geometry and Applications*, 17
(2007), 71-103.

"Is it really easy to get it compiled under (Ubuntu-)Linux?"
Some modifications are required to make it work. I created a patch today
for www.cs.umd.edu/~mount/Projects/ISODATA/Std_Hyb.tar.gz, now it compiles
and runs fine on my Ubuntu 12.04 32-bit machine. It is in the attachments.
I hope if it works for you too.

Thanks,
Himanshu
