Waifu2x

Waifu2x is an AI algorithm that upscales anime images. Waifu2x uses a convolutional neural network to process images, allowing it to recognize patterns within them and accurately upscale them while preserving details and reducing noise. It is outdated and generally inferior to Real-ESRGAN. It gets its name from the term 'waifu' since it was designed to upscale art of people's waifus.
