Saikat Dutta, Sourya Dipta Das, Nisarg A. Shah and Anil Kumar Tiwari

Accepted at Mobile AI workshop, co-located with CVPR 2021 Paper | ArXiv | Supplementary | YouTube

Pytorch 1.1.0 Torchvision 0.3.0 skimage 0.16.2

Colab demo

1. Dataset:

Get the EBB! dataset by registering here.

Train split: data/train.csv

Test split (val294 set): data/test.csv

2. Run inference on Val294 set using DMSHN model:

python DMSHN_test.py

3. Run inference on Val294 set using Stacked DMSHN model:

python stacked_DMSHN_test.py

4. To generate PSNR, SSIM and LPIPS scores on output images:

python eval.py -d0 OUT_DIR -d1 GT_DIR --use_gpu
