For this project, I gathered images of abstract paintings from WikiArt.org, processed them, and fed them into StyleGAN2 at the size of 1024x1024. I trained the GAN for three weeks on a GPU using Google Colab. I then processed the output images by adjusting the aspect ratio and running them through another ANN for a super-resolution resize. The resultant images are 4096 pixels wide or tall, depending on the aspect ratio.
