- Abstract summary: CNN-based methods for image deraining have achieved excellent performance in terms of reconstruction error as well as visual quality.
Due to challenges in obtaining real world fully-labeled image deraining datasets, existing methods are trained only on synthetically generated data.
We propose a Gaussian Process-based semi-supervised learning framework which enables the network in learning to derain using synthetic dataset.

- Abstract: Recent CNN-based methods for image deraining have achieved excellent
performance in terms of reconstruction error as well as visual quality.
However, these methods are limited in the sense that they can be trained only
on fully labeled data. Due to various challenges in obtaining real world
fully-labeled image deraining datasets, existing methods are trained only on
synthetically generated data and hence, generalize poorly to real-world images.
The use of real-world data in training image deraining networks is relatively
less explored in the literature. We propose a Gaussian Process-based
semi-supervised learning framework which enables the network in learning to
derain using synthetic dataset while generalizing better using unlabeled
real-world images. Through extensive experiments and ablations on several
challenging datasets (such as Rain800, Rain200H and DDN-SIRR), we show that the
proposed method, when trained on limited labeled data, achieves on-par
performance with fully-labeled training. Additionally, we demonstrate that
using unlabeled real-world images in the proposed GP-based framework results in
superior performance as compared to existing methods. Code is available at:

Our dataset uses two unpaired frames from real data and creates pairs of frames by simulating random warps.
We thus obtain the benefit of directly training on real data while having access to an exact ground truth.
