KMeansClassification Centroids

Dear all,

I do not understand what is the “centroids” file created as an output at the end of an unsupervised kmeans classification using the module “KMeansClassification”. I had the hope it was the “centres” of the different classes on the different bands but it is not.
So, what are these centroids?

Thanks in advance

Paul

Hello,

KMeansClassification normalizes the input image before applying the kmeans algorithm, so I think the centroid file contains the normalized centers of the classes.
