Estimating object speed in visual scenes is a critical part of perception. While various aspects of speed computation including …

Under natural viewing conditions, large eye movements are interspace by small eye movements (microsaccade). Recent works have shown …

This work extends the MotionClouds dynamic texture model testing aspects of its parametrization with an application in psychophysics.

Humans are able to interact successfully with moving objects in our dynamic world and the visual system effi ciently performs the …

The visual system does not process information instantaneously, but rather integrates over time. Integration occurs both for stationary …

In order to analyze the characteristics of a rich dynamic visual environment, the visual system must integrate information collected at …

Choosing an appropriate set of stimuli is essential to characterize the response of a sensory system to a particular functional …

Under natural viewing conditions, small movements of the eyes prevent the maintenance of a steady direction of gaze. It is unclear how …

To measure speed and direction of moving objects, the cortical motion system pools information across different spatiotemporal …

Moving objects generate motion information at different scales, which are processed in the visual system with a bank of spatiotemporal …

In order to analyze the characteristics of a rich dynamic visual environment, the visual system must integrate information collected at …

Oriented edges in images of natural scenes tend to be aligned in collinear or co-circular arrangements, with lines and smooth curves …

Neurons in the input layer of primary visual cortex in primates develop edge-like receptive fields. One approach to understanding the …

Integrating information is essential to measure the physical 2D motion of a surface from both ambiguous local 1D motion of its …
