I'm wanting to use BoofCV with Processing, but its recognition of any size of ArUco markers generated by this tool is unstable. Is there a resource or an app where I can get or generate a collection of markers that will be consistently recognized by BoofCV in Processing?
BoofCV doesn't work with Aruco Markers, yet at least. It's been on the wish list for a while now since everything needed to process Aruco Markers is there but it doesn't support their dictionaries.

Instructions for creating BoofCV markers is there. Basically you can use a command line tool for creating PDFs. There might even be a GUI, I can't remember, but it's not difficult.
