Nowadays, The wide adaptation of (Generative Adversarial Network)GAN has gained the attraction of researchers in the Single Image Super-Resolution (SISR) image. With the help of this model and the SISR concept, you will be generated data in different resolutions and used in data set annotation.
For e.g, in face alteration and face aging.
Extended work in GAN in natural-looking face image generation by the state-of-the-art models:
