Hi,
I have a 2D picture which, in general, looks like 3 hills with 2 valleys in between (there is no full seperation between the hills).
When running the 'kmeans' function with 3 clusters, I expected the Matlab to identify each "hill" in a different cluster.
However, the picture was partitioned into 3 horizontal areas.
Does anyone have an idea what I am doing wrong?
