Nice, @quark!

This could also be done with the ImageJ implementation of Median Cut.

- [https://imagej.nih.gov/ij/source/ij/process/MedianCut.java](https://imagej.nih.gov/ij/source/ij/process/MedianCut.java)

The nice thing about that implementation is it is based on java.awt.Image, so it takes a pixels[] array – no 2D conversion class required.
