Sujoy,

I skimmed the datamining web site for about 20 seconds, but I wasn't
clear what you were trying to call.  Can you be more specific about
what issue you ran into with this?

I would add that GRASS includes some different clustering/classification
algorithms though they are GPLed so it would not be possible to incorporate
them into the core of OpenEV.  They could be marshalled into a demand
loaded external module or something though.

Simple isodata clustering is relatively easy to write from scratch.

Best regards,
