You can use the code in the referred blogpost in your existing application. If you'd like to compile the whole code (containing K-Means clustering and some more operations) you can download the Ispe development source code on my downloads page. Cheers, Patrick Akash,

I cannot see how far you already are with your issue. What kind of info do you have? As an example: Let's say you have information on top speed of your car dataset. By setting your K to 2, you will end up with two clusters of cars. In a more concrete way: if the top speeds range from 120 to 240 miles per hour, with a traditional K-Means clustering and a K of 2, you will end up with the following two clusters: Cluster 1: top speeds from 120 to 180 Cluster 2: top speeds from 180 to 240 Adaptive K-Means clustering would try to find the best K for your dataset. In contrary to traditional K-Means clustering, it actually looks at, and uses the data to determine the optimal K. Kiran,

You could of course just pick both classes and place them into your own code / package hierarchy. Basically you need only those two classes. Just make sure that you specify the path to these classes according to where you've placed them. Then just perform the operation on a BufferedImage like so: action = new KMeansAction(BufferedImage image, int bins, int[]histogram, int initway); result = action.getResultImage(); in which result will contain the resulting BufferedImage.

Exeception thread "main" NoClassDefFoundError.. i think that means Class KMeanAction doesnt defined.. please reply me soon sir,,,, or tell me the correct way to do that procedures.. 1. in what name i want to save ... 2.where i put the cluster class code.. 3.how to give the input... Dear sir .

thanks for ur reply..
i have saved in KMeanAction which is class name ..

but it will give error …

Exeception thread “main” NoClassDefFoundError..

i think that means Class KMeanAction doesnt defined..

please reply me soon sir,,,,

or tell me the correct way to do that procedures..
1. in what name i want to save …
2.where i put the cluster class code..
3.how to give the input…

The error you supply is completely generic. I can't relate it directly to the code supplied with these posts. Apparently some class definition is missing. Please check if all classes are defined correctly. Cheers, Patrick dharma,
