A Sliced Wasserstein Loss for Neural Texture Synthesis

This is an unofficial JAX implementation for A Sliced Wasserstein Loss for Neural Texture Synthesis (CVPR'21).

Please see here for the author's repository and cite them:

Notes

We require these libraries:

pip install -U "jax[cuda]" equinox optax tqdm pillow

The pre-trained VGG weights vgg19.npy is ported from the vgg19.pth file provided in the official repo.

We re-write the VGG network and Slice Wasserstein Loss in JAX code.

Run

python texsyn.py --exemplar_path data/input.png --loss_type sw

Results

Input	Output (Slice)	Output (Gram)

Last words

Thanks all efforts put on making all mentioned repositories public.

We appreciate bug reports. I will fix them when I make time around.
