Toward a Perceptual Space for Gloss
This comprehensive study of the perception of gloss is the largest of its kind to date and the first to use real material measurements. The authors also develop a novel multi-dimensional scaling algorithm for pairwise comparisons and construct a low-dimensional perceptual space for gloss.
Effects of Global Illumination Approximations on Material Appearance
In psychophysical experiments, this investigation explored the relationships between rendering parameters, object properties, and image fidelity in virtual-point light-rendering algorithms. The results find the ranges of parameters that produce images visually equivalent to reference images. This work provides strong perceptual grounding for an efficient class of global-illumination rendering algorithms.
Subtle Gaze Direction
Gaze direction is a novel technique that combines eye-tracking with subtle image-space modulation to direct viewer gaze about a digital image. It has potential applications in many areas, including large-scale display systems, perceptually adaptive rendering, and complex visual search tasks.
Apparent Display Resolution Enhancement for Moving Images
This paper shows that subpixel image motion can increase the perceived resolution on high-refresh-rate displays. By sequentially displaying images optimized for this purpose at the display resolution, subpixel details can be resolved at the retina in the region of interest due to fixational eye tracking of this region.
