Center node: "style based variational autoencoder for real world super resolution"
  Abstract: Real-world image super-resolution is a challenging image translation problem. Low-resolution (LR) images are often generated by various unknown transformations rather than by applying simple bilinear down-sampling on HR images. To address this issue, this paper proposes a novel Style-based Super-Resolution Variational Autoencoder network (SSRVAE) that contains a style Variational Autoencoder (styleVAE) and a SR Network. To get realistic real-world low-quality images paired with the HR images, we design a styleVAE to transfer the complex nuisance factors in real-world LR images to the generated LR images. We also use mutual information estimation (MI) to get better style information. For our SR network, we firstly propose a global attention residual block to learn long-range dependencies in images. Then another local attention residual block is proposed to enforce the attention of SR network moves to local areas of images in which texture detail will be filled. It is worth noticing that styleVAE is presented in a plug-and-play manner and thus can help to promote the generalization and robustness of our SR method as well as other SR methods. Extensive experiments demonstrate that our SSRVAE surpasses the state-of-the-art methods, both quantitatively and qualitatively.
