NTIRE 2023 Video Colorization Challenge @ CVPR 2023

Track 1: Fréchet Inception Distance (FID) Optimization

Please visit test_NTIRE23_Track_1_FID.py to evaluate our model.

We provide the colorized images HERE, and the reference images used to obtain the results HERE.

⚡ Quick Inference

• Download Pre-trained Models: download a pretrained colorization model from the tabulated links, and put it into the folder ./BiSTNet-NTIRE2023/, like ./BiSTNet-NTIRE2023/checkpoints , ./BiSTNet-NTIRE2023/data and ./BiSTNet-NTIRE2023/models/protoseg_core/checkpoints .
• Prepare Testing Data: You can put the testing images in a folder, like ./demo_dataset.
  • demo_dataset/input: the directory of input grayscale images.
  • demo_dataset/ref: the directory of reference images (only f001.png, f050.png and f100.png are colorful images).
  • demo_dataset/output: the directory to save the colorization results.
• Test on Images:

conda activate bistnet && cd BiSTNet-NTIRE2023
CUDA_VISIBLE_DEVICES=0 python test_NTIRE23_Track_1_FID.py

For more details please refer to test_NTIRE23_Track_1_FID.py.
