This folder contains a dataset used for evaluation of the NoRM metric, as well as results of the study. Please refer to the paper (and supplemental material) entitled "NoRM: No-Reference Image Quality Metric for Realistic Image Synthesis" for additional information (http://www.mpi-inf.mpg.de/resources/hdr/norm). You can also contact Martin Cadik by an email (mcadik@mpi-inf.mpg.de). Directory structure: stimuli this folder contains 2 subfolders: -reference images (subfolder 'ref') -distorted images, i.e. images exhibiting rendering artifacts (subfolder 'dst') both the reference and distorted images should be presented at a calibrated LDR display metrics this folder contains the responses of 2 full-reference image quality metrics HDR-VDP2 (suffix 'HDR-VDP2'), and SSIM (suffix '_SSIM') and responses of no-reference metric NoRM (suffix '_NoRM') and NoRM after perceptual normalization (suffix '_NoRM_perceptual) subjects this folder contains average subjective responses (suffix '_avg'), false-color visualizations (suffix '_vis') and standard deviations (suffix '_std') for 'no-reference' and 'with-reference' experiments additionally, there are 10 subfolders ('001'-'010') for each experiment containing the responses of a particular subject
