DPSR

Deep Plug-and-Play Super-Resolution for Arbitrary Blur Kernels (CVPR, 2019)

Training and testing codes for the super-resolver prior (PyTorch)

The left is the blurry LR image. The right is the super-resolved image by DPSRGAN with scale factor 4.

Run demo_test_dpsr.py to produce the following results.
