PyTorch Image Quality (PIQ)

PIQ (PyTorch Image Quality) is a collection of measures and metrics for automatic image quality assessment in image-to-image tasks such as denoising, super-resolution, and image generation. Currently at version 0.8.0, the library offers both functional interfaces for calculating metrics and PyTorch modules for using them as loss functions. It has a regular release cadence, with minor versions released every 1-2 months, continually extending its set of measures and metrics.
