waifu2x is an image scaling and noise reduction program for anime-style art and other types of photos.

waifu2x was inspired by Super-Resolution Convolutional Neural Network (SRCNN). It uses Nvidia CUDA for computing, although alternative implementations that allow for OpenCL and Vulkan have been created.

Etymology

Waifu (from the Japanese pronunciation of "wife") is anime slang for a female character to whom one is attracted. 2x means two-times magnification.

Example

• Middle: 256×256px, JPG quality 30%, then nearest-neighbor interpolation
• Right: 512×512px, waifu2x upscaling & noise reduction
