This is a reimplementation of waifu2x (original) converter function, in C++, using OpenCV. This is also a reimplementation of waifu2x python version by Hector Martin. You can use this as command-line tool of image noise reduction or/and scaling. This software was originally made by @WL-Amigo and has been improved a lot over the years, see for more info on that. This build should support both CUDA for nVidia and OpenCL for AMD, nVidia & Intel HD.

Usage of this program can be seen by executing waifu2x-converter-cpp --help

What's New:

  • Added Unicode support (#90) Thanks a lot @YukihoAA


  • Nvidia users need at least driver version: 411.3 to use CUDA
