Unsupervised real world super resolution (USR) aims at restoring
high-resolution (HR) images given low-resolution (LR) inputs when paired data
is unavailable. One of the most common approaches is synthesizing noisy LR
images using GANs and utilizing a synthetic dataset to train the model in a
supervised manner. The goal of modeling the degradation generator is to
approximate the distribution of LR images given a HR image. Previous works
simply assumed the conditional distribution as a delta function and learned the …
