Segmentation error and num_cluster

[Carlos Leandro]

Hello everybody

I'm trying to segment an image, but it's giving this error. It only segments if the nun_clust is below 5 and the segmentation is horrible,

The error is this

rsgislib.imagecalc.kmeans_clustering(
_imagecalc.error: All data points are already assigned to cluster centres. Not enough unique cluster centres. swig/python detected a memory leak of type 'OSRSpatialReferenceShadow *', no destructor found.
swig/python detected a memory leak of type 'OSRSpatialReferenceShadow *', no destructor found.

Thanks

Hi.

What is the image you are trying to segment?

Is the no data value appropriately set in the input image as the normalisation (stretch) might be messing up the imagery if the no data value has not been set.

Cheers Pete
