QualityScaler is a Python-based Windows application that applies AI models to enhance, upscale, and denoise photographs and videos. It leverages PyTorch and ONNX runtime to run pre-trained super-resolution models including Real-ESRGAN, BSRGAN, and IRCNN for tasks like noise reduction and compression artifact removal. The app supports GPU acceleration from NVIDIA, AMD, and Intel, and handles both image and video processing.
