Quality-Aware Unpaired Image-to-Image Translation [PDF]

IEEE Transactions on Multimedia, 2019
Generative Adversarial Networks (GANs) have been widely used for the image-to-image translation task. While these models rely heavily on the labeled image pairs, recently some GAN variants have been proposed to tackle the unpaired image translation task.
