Single Image Reflection Removal with Edge Guidance, Reflection Classifier, and Recurrent Decomposition (WACV 2021 accepted)

PyTorch implementaton of the following paper. In this paper, we propose a novel model with auxiliary techniques to tackle the problem of single image reflection removal.

<div align=center><img height="300" src="https://github.com/JennaChangY/Reflection-Removal-with-Auxiliary-Techniques/blob/main/teaser.png"/></div> Given a reflection contaminated input image (the first column), our method aims to decompose the reflection layer (the last column) and generate the reflection-free transmission layer (the third column), which must be quite similar to its corresponding groundtruth (the second column).

Testing

Download our pretrained models from here and put them under weights/.
Run the sample data provided in this repo:

python test.py

Run your own data:

python test.py --data_dir YOUR_DATA_PATH
               --save_dir YOUR_SAVE_PATH

Training

Create the synthetic training data,

images from 2012 PASCAL VOC training images with the generation method from CEILNet.
images on Flickr with the generation method from Zhang et al.

Download the real-world training data obtained from Zhang et al. and apply typical data augmentation techniques (flipping and random cropping).
Or you can download whole training dataset here and put them under train_data/.
Then directly run the training code:

python train.py
