The goal of supercells is to utilize the concept of superpixels to a variety of spatial data.
Hi @ailich, see https://github.com/Nowosad/supercells/tree/estimate_compactness. I took your code, cleaned it a bit, decided to return all the values (and not just summaries), and added an R function `run_ce()` -- try...

In the original [Achanta et al 2012 paper](https://doi.org/10.1109/TPAMI.2012.120) they state "simply defining D to be the five-dimenensional Euclidean distance in labxy space will cause inconsistencies in clustering behavior for different...
@Nowosad, would these same parameters work for tuning `compactness`? And if so, would you be able to provide some guidance on how to choose the range of values to test?...

Have you tried comparing `supercells` with other raster segmentation methods? From my experience, I had very good results using simple clustering with pixel coordinates (rows, columns) in soil mapping project.
Thanks for this great package! There are a lot of interesting applications in soil science. Is `avg_fun` applied to the original grid values, or values after `transform` is applied? I'm...
