thanks for ur replay but am doing this project in brain tumour detection so k-means segmentation must cluster out the tumour part since it is more brighter than the other side in mr image

I understand what you are trying to do.

 

You are using the k-means.vi from the MLT in segmen.vi ‏29 KB

it looks like you are having trouble to set it up properly -

the link I posted in my previous post contains a working example using exactly that k-means.vi including example images.

 

How about you post a typical example image of your application?

Hi Nardimes,

you force me to guess what you want to do.

It is pretty likely, that you want to segment the bright pixels - which I suppose to be a tumor (foreground) - from the rest of the image (background)

 

 

If that is the case, this is a non-trivial task to do.

This is because in both images  those tumor-grey-values  occur in more than one region.

You need to choose a different segmentation approach,

or introduce more steps in your image processing, e.g.

distinguish between object and no-object pixels,

define a region of interest with-in the ovject pixel-region.....

 

I can not help you with that
