Query: Attention-based Adaptive Selection of Operations for Image Restoration
  in the Presence of Unknown Combined Distortions   Many studies have been conducted so far on image restoration, the problem of
restoring a clean image from its distorted version. There are many different
types of distortion which affect image quality. Previous studies have focused
on single types of distortion, proposing methods for removing them. However,
image quality degrades due to multiple factors in the real world. Thus,
depending on applications, e.g., vision for autonomous cars or surveillance
cameras, we need to be able to deal with multiple combined distortions with
unknown mixture ratios. For this purpose, we propose a simple yet effective
layer architecture of neural networks. It performs multiple operations in
parallel, which are weighted by an attention mechanism to enable selection of
proper operations depending on the input. The layer can be stacked to form a
deep network, which is differentiable and thus can be trained in an end-to-end
fashion by gradient descent. The experimental results show that the proposed
method works better than previous methods by a good margin on tasks of
restoring images with multiple combined distortions.
