Abstract

For the problem of image degradation caused by raindrops attached to the lens or glass surface, this paper proposed a multi-stage progressive image raindrop removal method which divides the raindrop removal process into multiple stages to easily implement. Firstly, it designed the multi-scale fused encoder-decoder network at each stage to learn raindrop features, and constructed multi-scale dilated convolutions with gated recurrent units to refine the internally transferred spatial features. In addition, it introduced the no dimensionality reduction channel attention module to extract channel information under specific spatial features. Finally, this paper adopted cross-stage feature fusion mechanism to strengthen the information exchange between the parts of each stage, and added horizontal connections between the encoder-decoder networks in each stage to realize the horizontal transfer of feature information. And it added a supervised attention module to enhance the information transmission between different stages, and progressively achieved the raindrop removal. Experiments show that the proposed method can effectively remove raindrops.
