A K-Means++ Clustering Implementation for VTK

K-Means clustering is an excellent technique for clustering points when the number of clusters is known. We present a implementation (vtkKMeanClustering) of the algorithm written in a VTK context. We also implement the K-Means++ initialization method which finds the global optimum much more frequently than a naive/random initialization.

The code is currently hosted at http://github.com/daviddoria/KMeansClustering .

A Must Have!!!

Free comment :
Once again: excellent work!

I have to admit that I have not read the paper yet, but I had a quick look to the code...



Using a kd-tree to find closest points will significantly speed up the implementation 

whenever the number of clusters is quite large.



I would also recommend that you abstract the metric and the way to compute the centroid, 

like that if someone wants to use L_1 or another metric (for example which makes use of normals) 

he won't need to duplicate too much code.
