Superposition of Time‐Interval Pitch Percepts

Pitch determination based on waveform superposition

Strong percepts of motion through depth without strong percepts of position in depth.

Encoding the motion of objects through three spatial dimensions is a fundamental challenge for the visual system. Two binocular cues could contribute to the perception of motion through depth: changes in horizontal disparity (CD) and interocular velocity differences (IOVD). Although conceptually distinct, both cues are typically present when real objects move. Direct experimental isolation of t...

Modeling color percepts of dichromats

Protanopes and deuteranopes, despite lacking a chromatic dimension at the receptor level, use the color terms "red" and "green", together with "blue" and "yellow", to describe their color percepts. Color vision models proposed so far fail to account for these findings in dichromats. We confirmed, by the method of hue scaling, the consistent use of these color terms, as well as their dependence ...

Brightness Illusions as Optimal Percepts

We show that Mach bands and a number of other low-level brightness illusions can be accounted for by assuming that the perceptual system performs simple Bayesian inference using a Gaussian image prior with noisy retinal gangion cells. This theory accounts for phenomena which have proven problematic for simple energy-based and lateral-interaction models while avoiding the complexities of mid-lev...

Evaluating Performance of Algorithms in Lung IMRT: A Comparison of Monte Carlo, Pencil Beam, Superposition, Fast Superposition and Convolution Algorithms
