Recovering Raindrop Removal Images under Heavy Rain

In this paper, we propose a new method for removing raindrops in images under heavy rain. When we drive in heavy rain, the raindrops attached to the windshield form a film and our visibility degrades drastically. In such situations, the existing raindrop removal methods cannot recover clear images, since these methods assume that the background scene is visible through the gap between the raindrops, which does not happen anymore in heavy rain. Thus, we in this paper propose a new method for recovering raindrop removal images under heavy rain from sequential images by using conditional GAN. The results of our experiments on real images and synthetic images show that the proposed method outperforms the state-of-the-art raindrop removal method.
