Solving K-means issue

Hi,
I'm trying to use K-means to segment and image and then working on the resulting mask to clean it up, but K-means doesn't seem to give a fixed output everytime the script is executed so I'm not able to work on the resulting images correctly. How do I ensure that the output remains the same everytime ?

It should, unless you've varied something, like the image you're processing, or the initial set of means. Does your script ask the user for any input (like filename, etc.), or use any random numbers?

Are you using some code or function from the Statistics Toolbox? I don't have that but if you edit your question to include it then maybe someone can reproduce it. Use a standard demo image that everybody has (because it ships with MATLAB) if you can.

The k-means algorithm involves random cluster initialization unless you provide initial cluster centers.
