Progressions.

In this post, we compare portraits generated by a neural style transfer algorithm with VGG-19 CNN network and StyleGAN2 trained on FFHQ (Flickr-Faces-HQ). The input for the first algorithm is a minimal sketch, while the input for the second one is the output portrait of the previous system.
