Description

RAID (Responses to Affine Image Distortions) is a perceptual image quality database built from human judgments. Unlike traditional databases focused on digital distortions, RAID investigates suprathreshold affine transformations — rotation, translation, scaling, and Gaussian noise — which are more representative of distortions encountered in natural viewing conditions.

Subjective perceptual scales were collected using the psychophysical method Maximum Likelihood Difference Scaling (MLDS). Over 40,000 image comparisons were performed by 210 human observers under controlled laboratory conditions.
