For what it's worth, attached is a KNN demo, though for (x,y) points, not for an image.
For image processing, you need to decide upon what features you're going to use. What are you going to cluster on? What values are your reference set?

For what it's worth (very little since kmeans is usually lousy, or at least not the best method, for intensity segmentation), I'm attaching my demo on using kmeans to do color segmentation.
