After seeing Doom Neural Upscale 2X by hidfan, I became interested in testing out “super resolution” techniques on the images found in Rainbow Six and Rogue Spear.
Super Resolution is the process of taking a smaller image and generating extra detail to output a larger resolution image without just blurring the smaller image. Although there are many varied techniques to achieve the results, in this article I will be using an open source trained network, ESRGAN (Enhanced SRGAN), and an image upscaling service called LetsEnhance.io.
