dists-pytorch

IQA: Deep Image Structure and Texture Similarity Metric

piqa

PyTorch Image Quality Assessement package

image-quality

Image quality is an open source software library for Image Quality Assessment (IQA).

viqa

A python package for volumetric Image Quality Assessment

qualisr-lab

Python toolkit for extracting IQA features, training regressors, and analyzing super-resolution image quality against human scores.

blur-detector

python implementation of the paper "Spatially-Varying Blur Detection Based on Multiscale Fused and Sorted Transform Coefficients of Gradient Magnitudes" - cvpr 2017

pybrisque

A python implementation of BRISQUE Image Quality Assessment

stlpips-pytorch

[ECCV 2022] We investigated a broad range of neural network elements and developed a robust perceptual similarity metric. Our shift-tolerant perceptual similarity metric (ST-LPIPS) is consistent with human perception and is less susceptible to imperceptible misalignments between two images than existing metrics.
