Comparison of the Detection Sensitivities of Human and Full-Reference Image Quality Assessment Models to Distortions in Natural and Non-natural Images
Measure JND by Psychopy
We decide to use 2AFC (Two-Alternative Forced Choice)
QUEST procedure (a bayesian adaptive psychometric method)
Find the Just noticeable difference (JND)- minimum detectable distortion intensity
Heeger-Bergen texture synthesis algorithm
Retain the first-order statistics of both its pixel intensity and responses to multi-orientation and multi-scale filters
Models
Traditional:
MSE, NLPD : low-level features
SSIM, MS SSIM: structure information
DL-based:
LPIPS: deep features extracted by VGG-16
DISTS: the combination of deep features and structure information
