Information

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

  • JPEG ;
  • JPEG2000 ;
  • LAR coding ;
  • Blurring.

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.

A Microsoft Excel worksheet, giving all subjective quality scores is included in the above archive.
