Run test

• Install Caffe, Matlab R2013b
• Run testing:

$ cd ./test
$ matlab
>> test_IDN

Note: Please make sure the matcaffe is complied successfully.

./test/caffemodel/IDN_x2.caffemodel, ./test/caffemodel/IDN_x3.caffmodel and ./test/caffemodel/IDN_x4.caffemodel are obtained by training the model with 291 images, and ./test/caffemodel/IDN_x4_mscoco.caffemodel is got through training the same model with mscoco dataset.

The results are stored in "results" folder, with both reconstructed images and PSNR/SSIM/IFCs.

Train

• step 1: Compile Caffe with train/include/caffe/layers/l1_loss_layer.hpp, train/src/caffe/layers/l1_loss_layer.cpp and train/src/caffe/layers/l1_loss_layer.cu
• step 2: Run data_aug.m to augment 291 dataset
• step 3: Run generate_train_IDN.m to convert training images to hdf5 file
• step 4: Run generate_test_IDN.m to convert testing images to hdf5 file for valid model during the training phase
• step 5: Run train.sh to train x2 model
