PyTorch Toolbox for Image Quality Assessment

pyiqa is a comprehensive PyTorch-based toolbox for Image Quality Assessment (IQA), offering reimplementations of numerous mainstream full-reference (FR) and no-reference (NR) metrics. It aims for GPU acceleration, often outperforming MATLAB counterparts, and provides calibrated results against official scripts where available. The library is actively maintained with frequent releases, adding new metrics, features, and bug fixes.
