Image Denoising via Multi-Scale Gated Fusion Network

Deep convolutional neural networks have made significant progress in image denoising.However, in most ultrastar dc hc550 cases, denoising methods using a single-stream structure with a single kernel size do not perform so well in integrating complementary contextual information; owing to the lack of this type of information, they may fail to reconstruct fine textures and patterns.To address this problem, we propose a multi-scale gated fusion network (MGFN) for image denoising, which learns direct end-to-end mappings from corrupted images to clean images.

Our proposed network consists of several multi-scale mutually-gated (MM) blocks.In each MM block, we incorporate dilated convolution into a merge-and-run (MR) here module to exploit multi-scale features in an effective way and further recognize useful features by filtration via a gating mechanism.Moreover, we propose a simple but effective loss function named dropout-loss to train the network.

The extensive experiments on benchmark datasets show that our proposed method can well recover textures, yielding favorable performance against other state-of-the-art methods.
