Virtual reality (VR) is becoming an increasingly important way to investigate sensory
processing. The converse is also true: in order to build good VR technologies, one needs an …

An ideal observer is a theoretical model observer that performs a specific sensory-
perceptual task optimally, making the best possible use of the available information given …

Quality assessment of 3D images encounters more challenges than its 2D counterparts.
Directly applying 2D image quality metrics is not the solution. In this paper, we propose a …

Climatic change is widely acknowledged to have played a role in the dispersal of modern
humans out of Africa, but the timing is contentious. Genetic evidence links dispersal to …

A great challenge of systems neuroscience is to understand the computations that underlie
perceptual constancies, the ability to represent behaviorally relevant stimulus properties as …

Virtual reality (VR) allows us to create visual stimuli that are both immersive and reactive. VR
provides many new opportunities in vision science. In particular, it allows us to present wide …

The processing of visual information by the nervous system requires significant metabolic
resources. To minimize the energy needed, our visual system appears to be optimized to …

Summary In Li and Atick's [1, 2] theory of efficient stereo coding, the two eyes' signals are
transformed into uncorrelated binocular summation and difference signals, and gain control …

Binocular rivalry is a fascinating, widely studied visual phenomenon in which perception
alternates between two competing images. This experience, however, is generally restricted …

Certain visual stimuli, such as striped patterns and filtered noise, have been reported to be
uncomfortable. Some filtered noise patterns judged as uncomfortable are those with a …
