Use oneStroke drawing, to draw a portrait.
All the implementations are in foo.py.
In dev branch, there is a GLHF/ folder containing a jupyter notebook that will help you get a better feeling of this implementation.
Unfortunately this implementation does not find a Euler path, even if the graph is somehow Eulerian graph. (by somehow I mean almost impossible, unless magic)
pip install -r requirements.txt
Basically, it's just opencv-python, numpy, scipy. Not too many dependencies. Actually, jupyter and matplotlib is also required if you want to dive in GLHF/ in the dev branch.
Good Luck Have Fun :)
The package is used on the robotics project to generate one stroke portrait path.
