Test the pre-trained models

Usage example to test HSCNN-D model for clean RGB images

cd hscnn-d_clean
cd inference/models && unzip *.zip && cd ../
/bin/bash demo.sh

Usage example to test HSCNN-D model for real-world RGB images

cd hscnn-d_real
cd inference/models && unzip *.zip
cat *.tar.gz.* | tar -xzv && cd ../
/bin/bash demo.sh

To access the validation dataset and the reconstructed results of HSCNN-D

Update 2019/06/05: Model-ensembled results of HSCNN-D are now replaced by the single-model ones (Table 3).

Train the model

Usage example to train a new model for clean RGB images

cd hscnn-d_clean/train && python train.py

Usage example to train a new model for real-world RGB images

cd hscnn-d_real/train && python train.py
