Color Image Segmentation with Dbscan


I am about to finde clusters in a image with the DBScan. To do so I have tried to adapt the workflow of christian.dietz from the entry “Applying cluster nodes on images”. Basically, I want to do what’s described here:
As I understand it, the main differences are that it is done by using HSV/HSB and that i want to use DBScan instead of k-means. Here is a example what it should look like:

I just replaced the k-means node with numeric distances and DBSCAN but it not working. Is that even the right approach?

Thanks for advice.

Yes I need to do it with DBscan
