## Model Weights
Download the checkpoints of RealDAN.
Put the downloaded checkpoints into [checkpoints](./checkpoints)
## Inference
For inference on Real-World images
```bash
cd codes/config/RealDAN
python3 inference.py \
--opt options/test/dan_edsr_gan_real.yml \
--input_dir=/dir/of/input/images \
--output_dir=/dir/of/saved/outputs
```
For inference on blurry images
```bash
cd codes/config/KernelDAN
python3 inference.py \
--opt options/test/x4.yml \
--input_dir=/dir/of/input/images \
--output_dir=/dir/of/saved/outputs
```
## Evaluation
For evaluation on DIV2K-Real, please download the dataset to your own path, and run
```bash
cd codes/config/RealDAN
python3 test.py \
--opt options/test/dan_edsr_gan_syn.yml
```
and
```bash
cd codes/config/RealDAN
python3 test.py \
--opt options/test/dan_edsr_syn.yml
```
For evaluation on DIV2KRK, please download the [dataset](http://www.wisdom.weizmann.ac.il/~vision/kernelgan/DIV2KRK_public.zip) to your own path, and run
```bash
cd codes/config/KernelDAN
python3 test.py \
--opt options/test/x2.yml
```
and
```bash
cd codes/config/KernelDAN
python3 test.py \
--opt options/test/x4.yml
```
