This data set shows glare comming from a large color light source affects detection thresholds at low luminance levels. The original data from: Mantiuk R, Rempel AG, Heidrich W. Display considerations for night and low-illumination viewing. In: Proc. of Symposium on Applied Perception in Graphics and Visualization - APGV ’09. 2009:53-58. link.
The stimuli are 1 cpd dark Gabor patches of background luminance of 0.002 cd/m2 seen in the presence of a strong source of glare. The prototype display with individually controlled red, green and blue LED backlight was used to create narrow bandwidth glare light.
This is the original Visual Difference Predictor based on corresponence with the author and the book chaper: Daly, S. "The Visible Differences Predictor: An Algorithm for the Assessment of Image Fidelity." In Digital Images and Human Vision, edited by Andrew B. Watson, 179-206. MIT Press, 1993.
The metric uses the default parameters from the paper except the masking slope, set to 0.9 for all bands, which was found from fitting the metric to the masking data sets. One optional component in the VDP is computing contrast in the cortex filtered images, which could be either global or local. This version uses global contrast.
The metric also includes an improved variation of the phase uncertainty, as described in: Lukin, A. "Improved Visible Differences Predictor Using a Complex Cortex Transform." In International Conference on Computer Graphics and Vision (GraphiCon), 2009. Phase uncertainty is not mentioned in the '93 book chapter, but is described in the patent application. The method proposed by Lukin achieves the same goals as phase uncertainty but is more elegant and efficient than the approach described in the patent.
