Create a Paint by Numbers script - Grasshopper - McNeel Forum

Hello GH community, I am trying to transform a picture into a “paint by numbers” (childhood nostalgia…) In photoshop for example, it can be made by using a cutout filter, to split the colors into sample. I would like to reproduce this cutout filter in grasshopper (using gh components only, not custom python/C++ scripts) I tried by using a voronoi pattern and merging the cells that are in the same domain of brightness but the result is not very satisfiying yet. Does anyone have ideas? Scrip
