PyTorch implementation for photorealistic style transfer that does not need any further post-processing steps; e.g. from day to sunset, from summer to winter, etc.
The code was written by Jaejun Yoo, Sanghyuk Chun, Youngjung Uh, and Byeongkyu Kang.
- PyTorch >= 0.4.1
- Check the requirements.txt
pip install -r requirements.txt
- Clone this repo:
git clone https://github.com/clovaai/WCT2.git
cd WCT2
- Pretrained models can be found in the
./model_checkpoints
- Prepare image dataset
- Images can be found in DPST repo
- To make a new dataset with label pairs, please follow the instruction of PhotoWCT repo
- Put the content and style images with their segment label pairs (if available) into the
example
folder accordingly. Currently there are several example images from DPST repo. - You can find the entire content and style images (with paired segmentation label maps) in the following link DPST images. input folder has the content images and the style folder has the style images. Every segmention map can be found in the segmentation folder.
- Finally, test the model:
python transfer.py --option_unpool cat5 -a --content ./examples/content --style ./examples/style --content_segment ./examples/content_segment --style_segment ./examples/style_segment/ --output ./outputs/ --verbose --image_size 512
The test results will be saved to ./outputs
by default.

: stylize at the decoder module-s
,--transfer_at_skip
: stylize at the skipped high frequency components-a
,--transfer_all
: stylize and save for every composition; i.e. power set of {-e,-d,-s})--cpu
: run on CPU--verbose

option_unpool = sum
version - Full stylization
python transfer.py --option_unpool sum -e -s --content ./examples/content --style ./examples/style --content_segment ./examples/content_segment --style_segment ./examples/style_segment/ --output ./outputs/ --verbose --image_size 512
- Low-frequency-only stylization
python transfer.py --option_unpool sum -e --content ./examples/content --style ./examples/style --content_segment ./examples/content_segment --style_segment ./examples/style_segment/ --output ./outputs/ --verbose --image_size 512
option_unpool = cat5
version
python transfer.py --option_unpool cat5 -a --content ./examples/content --style ./examples/style --content_segment ./examples/content_segment --style_segment ./examples/style_segment/ --output ./outputs/ --verbose --image_size 512
- Our implementation is highly inspired from NVIDIA's PhotoWCT Code.
