Hi all.

I have block from an image obtained using:

How best can I cluster similar blocks from my BlockImage matrix using: kmeans?

I also wish to display the distance between; any two intra-cluster blocks, any two blocks from different clusters; any two centroids if possible.

Honestly, am not so sure how to tackle this. Looking at the kmeans examples from the document, is not so intuitive for this particular scenario.

Thanks alot.

Not sure why you're using im2col().

Attached is my kmeans demo for a gray scale image, plus one for color and hyperspectral images.

you converted the distinct image blocks to a column matrix?

but seriously whats happening?
