News

(2022-05-16) Add x1 sr model. Add --tile_size to avoid OOM.

(2022-03-15) Add x4 sr model. Try --sr_scale.

(2022-03-09) Add GPEN-BFR-2048 for selfies. I have to take it down due to commercial issues. Sorry about that.

(2021-12-29) Add online demos Hugging Face Spaces. Many thanks to CJWBW and AK391.

(2021-12-16) Release a simplified training code of GPEN. It differs from our implementation in the paper, but could achieve comparable performance. We strongly recommend to change the degradation model.

(2021-12-09) Add face parsing to better paste restored faces back.

(2021-12-09) GPEN can run on CPU now by simply discarding --use_cuda.

(2021-12-01) GPEN can now work on a Windows machine without compiling cuda codes. Please check it out. Thanks to Animadversio. Alternatively, you can try GPEN-Windows. Many thanks to Cioscos.

(2021-10-22) GPEN can now work with SR methods. A SR model trained by myself is provided. Replace it with your own model if necessary.

(2021-10-11) The Colab demo for GPEN is available now google colab logo.

Usage

python pytorch cuda driver gcc

  • Clone this repository:
git clone https://github.com/yangxy/GPEN.git
cd GPEN
python demo.py --task FaceEnhancement --model GPEN-BFR-512 --in_size 512 --channel_multiplier 2 --narrow 1 --use_sr --sr_scale 4 --use_cuda --save_face --indir examples/imgs --outdir examples/outs-bfr
  • Colorize faces:
python demo.py --task FaceColorization --model GPEN-Colorization-1024 --in_size 1024 --use_cuda --indir examples/grays --outdir examples/outs-colorization
  • Complete faces:
python demo.py --task FaceInpainting --model GPEN-Inpainting-1024 --in_size 1024 --use_cuda --indir examples/ffhq-10 --outdir examples/outs-inpainting
  • Synthesize faces:
python demo.py --task Segmentation2Face --model GPEN-Seg2face-512 --in_size 512 --use_cuda --indir examples/segs --outdir examples/outs-seg2face
  • Train GPEN for BFR with 4 GPUs:
CUDA_VISIBLE_DEVICES='0,1,2,3' python -m torch.distributed.launch --nproc_per_node=4 --master_port=4321 train_simple.py --size 1024 --channel_multiplier 2 --narrow 1 --ckpt weights --sample results --batch 2 --path your_path_of_croped+aligned_hq_faces (e.g., FFHQ)

When testing your own model, set --key g_ema.

Please check out run.sh for more details.
