waifu2x-converter-cpp(1)                     DragonFly General Commands Manual


SYNOPSIS

       waifu2x-converter-cpp rescales images and removes noise using the power
       of convolutional neural networks. It was originally made for and works
       best on anime art, but it can be used on any type of drawing.

       It does not work well with any image though. It behaves quite poorly
       when faced with photographs or pixel art.


SUPPORTED PLATFORMS

       Being based on OpenCV, this waifu2x-converter-cpp works on any
       platform. However, you will have better results if you have a GPU,
       especially an NVIDIA GPU.

       OpenCL(AMD GPU) version achieves only 40% of peak performance
       (291GFLOPS @ A10-7850K).

       CPU only (Intel or AMD) is quite slow, but still works if you're
       willing to wait.


EXAMPLE

       waifu2x-converter-cpp -i maiwaifu.png --scale-ratio 2 -o maiwafu2x.png

       Creates maiwaifu2x.png at 2x the canvas size of maiwaifu.png

              Displays usage information and exits.


AUTHORS

       This is not the original waifu2x, this is the waifu2x reimplementation
       using OpenCV. However, its function is the same as the original
       waifu2x, with the benefit of working on more hardware. For example, the
       original waifu2x only works on NVIDIA GPUs, while this version works on
       AMD GPUs or even just CPU with no GPU (albeit slowly).

       The original waifu2x was written by nagadomi <nagadomi@nurs.or.jp>

       This OpenCV fork was written by tanakamura <tanakmura@gmail.com>
