Example Command
realsr-ncnn-vulkan.exe -i input.jpg -o output.png -s 4
Full Usages
Usage: realsr-ncnn-vulkan -i infile -o outfile [options]...
-h show this help
-v verbose output
-i input-path input image path (jpg/png/webp) or directory
-o output-path output image path (png/webp) or directory
-s scale upscale ratio (4, default=4)
-t tile-size tile size (>=32/0=auto, default=0)
-m model-path realsr model path (default=models-DF2K_JPEG)
-g gpu-id gpu device to use (default=0)
-j load:proc:save thread count for load/proc/save (default=1:2:2)
-x enable tta mode
-f format output image format (png/webp, default=ext/png)
input-path
andoutput-path
accept either file path or directory pathscale
= scale level, 4 = upscale 4xtile-size
= tile size, use smaller value to reduce GPU memory usage, default selects automaticallyload:proc:save
= thread count for the three stages (image decoding + waifu2x upscaling + image encoding), using larger values may increase GPU usage and consume more GPU memory. You can tune this configuration with "4:4:4" for many small-size images, and "2:2:2" for large-size images. The default setting usually works fine for most situations. If you find that your GPU is hungry, try increasing thread count to achieve faster processing.format
= the format of the image to be output, png is better supported, however webp generally yields smaller file sizes, both are losslessly encoded

Build from Source
- Download and setup the Vulkan SDK from https://vulkan.lunarg.com/
- For Linux distributions, you can either get the essential build requirements from package manager
dnf install vulkan-headers vulkan-loader-devel
apt-get install libvulkan-dev
pacman -S vulkan-headers vulkan-icd-loader
- Clone this project with all submodules
git clone https://github.com/nihui/realsr-ncnn-vulkan.git
cd realsr-ncnn-vulkan
git submodule update --init --recursive
- Build with CMake
- You can pass -DUSE_STATIC_MOLTENVK=ON option to avoid linking the vulkan loader library on MacOS
mkdir build
cd build
cmake ../src
cmake --build . -j 4
