3D Visual Discomfort Database


The production of high quality stereoscopic videos becomes more challenging than conventional 2D film shooting, since multi-camera aspects such as inter-camera positioning must be addressed. A major challenge is optimizing for the highest viewing comfort, best depth impression and high image quality aspects. Therefore, we have developed a small stereoscopic three-dimensional (S3D) video database with scenes of different content and characteristics. For all the videos, we provide subjective assessment data considering visual comfort, depth quantity and image quality. The resulting scores can be used to evaluate performance of quality metrics, visual discomfort prediction models and disparity mapping algorithms.

Video database


The database contains

  • Ten low-resolution (640x480), non-expert, high-motion, outdoor videos, captured by means of a Bumblebee 2 camera from Point Grey and re-rendered using two different depth comfort zones, see [A].
  • Eight high-resolution (1920x1080), expert, low-motion, indoor videos with four original videos from [1] and four re-rendered videos using our disparity mapping algorithm for quality optimization [A].
  • Three anaglyph videos for comparison of results from our optimization algorithm [A] and the one of Yan et al. [2].

Subjective assessment

17 subjects, from twenty five to fifty years old, participated in our subjective assessment. After testing them for stereo-blindness, colour-blindness and low vision according to [3], we had to break the experiment for three users because of low vision.

The videos were shown on a 55-inch stereoscopic display with the eyes of the viewer’s horizontal centred and 3.1 times the images height [1] away from the display.
Since, the subjective assessment aims at providing evidence regarding subjective image quality, depth quantity and visual comfort, discomfort, we designed four questions, similarly to [2], as follows:

  • Question 1: What is the level of image quality of the video (Bad-Poor-Fair-Good-Excellent)?
  • Question 2: What is the level of the depth quantity of the video (Bad-Poor-Fair-Good-Excellent)?
  • Question 3: What is the level of visual comfort associated with the video (Extremely uncomfortable-Uncomfortable-Mildly uncomfortable-Comfortable-Very Comfortable)?
