Deep Back-Projection Networks for Super-Resolution (CVPR2018)

Winner (1st) of NTIRE2018 Competition (Track: x8 Bicubic Downsampling)

Winner of PIRM2018 (1st on Region 2, 3rd on Region 1, and 5th on Region 3)

We also provide original Caffe implementation

Pretrained models and Results

Pretrained models (DBPNLL) and results can be downloaded from this link! https://drive.google.com/drive/folders/1ahbeoEHkjxoo4NV1wReOmpoRWbl448z-?usp=sharing

Dependencies

• Python 3.5
• PyTorch >= 1.0.0

Model types

1. "DBPN" -> use T = 7
2. "DBPNLL" -> use T = 10
3. PIRM Model -> "DBPNLL" with adversarial loss
4. "DBPN-RES-MR64-3" -> improvement of DBPN with recurrent process + residual learning
