Description

A video quality dataset with XR (AR/VR) display distortions was created to measure the effect of display distortions, such as colour fringes or dithering, on image quality.

The dataset consists of:

  • 14 reference videos at 1080p resolution, spanning real, rendered, and productivity content, which are typical for AR/VR applications.
  • 8 distortions (display artifacts):
    • Spatiotemporal dithering
    • Light source nonuniformity (LSNU)
    • Blur (MTF degradation)
    • Reduced contrast (elevated black level)
    • Waveguide nonuniformity (WGNU)
    • Dynamic correction error (DCE)
    • Color fringes
    • Chroma subsampling

The quality was measured in a controlled pairwise comparison experiment with 77 participants. The conditions (pairs of video clips) were selected using the ASAP active sampling technique [1] and then scaled to JOD units under Thurstone Case V assumptions [2] using the pwcmp software (https://github.com/mantiuk/pwcmp). Reference images have JOD==10 and distorted ones have JOD values lower than 10 (except for noisy results).
