Interesting. Iā€™m really surprised that just 68 image pairs (plus some fuzzing) were enough to train that model. :slight_smile:

68 image pairs make tens of thousands individual strokesā€¦

As this uses a neural network I think this post from @David_Tschumperle is the answer:

This is a bit simpler.

Using Engrave, hereā€™s the results I got. :slight_smile:

Why not the original target ones too. :slight_smile:

Those have a lot of double-lining that the Sketch Simplification algorithm is supposed to eliminate.

Maybe so, but a close approximation and with slider tweaking, could get even better results (didnā€™t really spend that much time playing with the sliders). :slight_smile:

I donā€™t think you need neural networks just to simplify double lining. Iā€™m a bit surprised, but the engrave filter here does a very good job. Adding some post-processing to the engrave filter should do the job as well.

This has helped me with an animation no very clean.
