How to use kmeans for an image

Hi..
I need to apply kmeans clustering for a grayscale image (the clustering should be based on the value of the pixels and not the distance). I tried to apply the inbuilt function to do that but the documentation says I will get only a n-by-1 vector as the output. How do I then get the cluster values for each of the pixels?
Thank you,
Mathew

Here's an example that you should be able to modify from color to grayscale rather easily: http://www.mathworks.com/products/demos/image/color_seg_k/ipexhistology.html

What do you mean by "the cluster values" ? kmeans() returns the cluster number for each point (each row is considered a point) as the first output. That kmeans() cannot return the cluster probabilities, but the four-output version will return the distance from each point to each centroid.
