Abstract

Convolutional neural networks (CNN) are becoming mainstream in computer vision. In particular, CNNs are widely used for high-level vision tasks, like image classification. This talk focuses on examples of using CNNs for image super-resolution (SR), which is a low-level vision task, and on practical aspects of training CNNs. U-Net architecture was published in 2015 and has been deployed in practice for image SR. RCAN (Residual Channel Attention Network) was published in 2018 and gives much superior results compared to U-Net at smaller network size. GANs have also been widely studied for image SR. Cycle GAN allows to learn image translation from low resolution space to SR space without paired data, which makes it interesting for practical applications where training data is scarce.
