Video Enhancement Based on Unpaired Learning

Distortion of real video is affected by many factors. Many existing old videos n have the problem of low definition. However, most video enhancement based on paired learning is trained for specific degradation problem, lack of the ability to enhance real low-definition video with unknown distortion. In this paper, we propose a joint video enhancement algorithm based on unpaired learning, which uses a high-definition video to enhance a low-definition video with similar contents. In order to train the network, we also build three pairs of unpaired video datasets with chimpanzee, city night view and military figures as contents. In experiments, we compare our method with enhancement algorithm based on paired learning and other unpaired framework and find that our method achieves a higher performance,
