This demo illustrates a simple and effective method for making local, semantically-aware edits to a target GAN output image. This is accomplished by borrowing styles from a reference image, also a GAN output.

The method requires neither supervision from an external model, nor involves complex spatial morphing operations. Instead, it relies on the emergent disentanglement of semantic objects that is learned by StyleGAN during its training, which we detect using Spherical k-means.

The implementation below relies on PyTorch and requires downloading additional parameter files .
