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 …

Visual motion processing can be conceptually divided into two levels. In the lower level,
local motion signals are detected by spatiotemporal-frequency-selective sensors and then …

Despite the fundamental importance of visual motion processing, our understanding of how
the brain represents basic aspects of motion is incomplete. While it is generally believed that …

A core goal of visual neuroscience is to predict human perceptual performance from natural
signals. Performance in any natural task can be limited by at least three sources of …

The 1/f α amplitude spectrum is a statistical property of natural scenes characterising a
specific distribution of spatial and temporal frequencies and their associated luminance …

Sensing the movement of fast objects within our visual environments is essential for
controlling actions. It requires online estimation of motion direction and speed. We probed …

We recorded horizontal ocular-following responses to pairs of superimposed vertical sine
wave gratings moving in opposite directions in human subjects. This configuration elicits a …

A common practice to account for psychophysical biases in vision is to frame them as
consequences of a dynamic process relying on optimal inference with respect to a …

When animal behavior is studied in a laboratory environment, the animals are often
extensively trained to shape their behavior. A crucial question is whether the behavior …

Motion direction discrimination becomes impaired when combinations of drifting high spatial
frequency (HSF) and static low spatial frequency (LSF) patterns are merged into a …
