Visible difference predictors (VDPs) are image or video difference metrics modeling perceptual aspects like foveation and spatio-temporal vision. The authors offer a technical overview of VDPs and a comparison to other metrics, ending with a practical guide to selecting the right VDP, and to high-confidence combinations of them with subjective testing.
24.2 - Interaction Between Duty Ratio and Eye Movement for Motion Artifacts (4:00 PM - 4:20 PM)

The authors investigate how display duty ratio affects motion artifact visibility. They ask participants whether a long or short duty ratio minimizes motion artifacts under five conditions of eye movements and stimulus motion. The responses are context-dependent, suggesting eye and stimulus motion must be considered in standardizing benchmarks for motion displays.
24.3 - Perceptual Consequences of Wobbulated Displays (4:20 PM - 4:40 PM)
-

-
One method of achieving higher resolution is pixel shift, or “wobbulation." The authors compare the perceptual performance of two wobbulated 4K projectors with a true 4K projector using triangle orientation discrimination and contrast sensitivity. True 4K consistently improves contrast sensitivity.
24.4 - Visual Optical Simulation System and Quantitative Evaluation Criteria (4:40 PM - 5:00 PM)

The image graininess of displays is a subjective indicator and is very difficult to evaluate quantitatively. The authors introduce a visual optical simulation system and quantitative evaluation criteria for graininess.
