The purpose of this page is to make available the subjective quality assessment IRCCyN/IVC database. The experiments were conducted in our lab in normalized conditions.

Content

10 original images were used, 235 distorted images were generated from 4 different processing:

These algorithms have the advantage to generate very different type of distortions. Subjective evaluations were made at viewing distance of 6 times the screen height using a DSIS (Double Stimulus Impairment Scale) method with 5 categories and 15 observers. Distortions for each processing and each image have been optimised in order to uniformly cover the subjective scale.
