cd ./Synthesis

• Constrcut these new folders for training and testing

  training set: trainA, trainB, trainC(contains real-world reflection images for adversarial loss.)

  testing set: testA(contains the images to be used as reflection.), testB(contains the images to be used as transmission.)

• To train the synthesis model:

python3 ./train.py --dataroot path_to_dir_for_reflection_synthesis/ --gpu_ids 0 --save_epoch_freq 1 --batchSize 10

or you can directly:

bash ./synthesis_train.sh

• To test the synthesis model:

python3 ./test.py --dataroot path_to_dir_for_synthesis/ --gpu_ids 0 --which_epoch 130 --how_many 1

or you can directly:

bash ./synthesis_test.sh

Here is the pre-trained model. And to generate the three types of reflection images, you can use these original images which are from perceptual-reflection-removal.

Due to the copyright, the real reflection images are not released here.

cd ./Removal

• Constrcut these new folders for training and testing

  training set: trainA(contains the reflection ground truth.), trainB(contains the transmission ground truth), trainC(contains the images which have the reflection to remove.), trainW(contains the alpha blending mask ground truth.)

  testing set: testB(contains the transmission ground truth), testC(contains the images which have the reflection to remove.)

• To train the removal model:

python3 ./train.py --dataroot path_to_dir_for_reflection_removal/ --gpu_ids 0 --save_epoch_freq 1 --batchSize 5 --which_type focused

or you can directly:

bash ./removal_train.sh

• To test the removal model:

python3 ./test.py --dataroot path_to_dir_for_reflection_removal/ --which_type focused --which_epoch 130 --how_many 1

or you can directly:

bash ./removal_test.sh

Here are the pre-trained models which are trained on the three types of synthetic dataset.

Here are the synthetic training set and testing set for reflection removal.

To evaluate on other datasets, please finetune the pre-trained models or re-train a new model on the specific training set.

Part of the code is based upon pytorch-CycleGAN-and-pix2pix.
