Perception of Visual Motion

Visual motion perception.

The primate visual motion system performs numerous functions essential for survival in a dynamic visual world. Prominent among these functions is the ability to recover and represent the trajectories of objects in a form that facilitates behavioral responses to those movements. The first step toward this goal, which consists of detecting the displacement of retinal image features, has been stud...

Optimizing Visual Motion Perception during Eye Movements

We usually perceive a stationary, stable world and we are able to correctly estimate the direction of heading from optic flow despite coherent visual motion induced by eye movements. This astonishing example of perceptual invariance results from a comparison of visual information with internal reference signals predicting the visual consequences of an eye movement. Here we demonstrate that the ...

A model of visual motion perception

The neural mechanisms underlying the segregation and integration of detected motion still remain unclear to a large extent. Motion of an extended boundary can locally be measured by neurons only orthogonal to its orientation (aperture problem) while this ambiguity is resolved for localized image features, e.g. corners or non-occlusion junctions. In this thesis, a novel neural model of visual mo...

Binocular visual surface perception.

Binocular disparity, the differential angular separation between pairs of image points in the two eyes, is the well-recognized basis for binocular distance perception. Without denying disparity's role in perceiving depth, we describe two perceptual phenomena, which indicate that a wider view of binocular vision is warranted. First, we show that disparity can play a critical role in two-dimensio...
