Real-CUGAN NCNN Vulkan is a command-line AI image upscaler for people enlarging anime artwork on their own computer. It uses Real-CUGAN models through the ncnn runtime to increase image resolution and reduce noise.
- Anime upscaling: Enlarge images at 2x, 3x or 4x resolution, or process them without changing their size.
- Adjustable denoising: Choose the strength of noise reduction or leave denoising disabled.
- Batch processing: Process individual images or whole directories, with JPG, PNG and WebP support for input and output.
- Hardware support: Run processing on Intel, AMD, NVIDIA or Apple Silicon GPUs through Vulkan, with CPU processing and multiple GPUs also supported.
The portable packages run locally on Windows, Linux and macOS and include the required models. Image processing stays on your machine, and you don't need a CUDA or PyTorch runtime. The software is open source under the MIT license.
It's a command-line tool, so it suits batch workflows and users comfortable working outside a graphical editor. Tile-based processing can reduce GPU memory use for large images.
