Visual System: Mapping of motion perception

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...

The visual perception of motion

Sensing the movements of the world and the objects within it appears to be a fundamental job for our visual system. In rare cases of brain damage, we find that individuals lacking motion perception live in a very different world of frozen images, where simple tasks like filling a kettle or crossing the road take on alarming difficulties. That tasks such as driving a fast car down the freeway re...

Auditory Motion Information Drives Visual Motion Perception

BACKGROUND Vision provides the most salient information with regard to the stimulus motion. However, it has recently been demonstrated that static visual stimuli are perceived as moving laterally by alternating left-right sound sources. The underlying mechanism of this phenomenon remains unclear; it has not yet been determined whether auditory motion signals, rather than auditory positional sig...

Towards a Hazard Perception Assistance System using Visual Motion

We report on preliminary work in the application of lowlevel visual motion cues to identify potential hazards during on-road driving. In conjunction with a clinical study of hazard perception in older age drivers, we consider the detection of a range of hazardous scenarios identified as particularly challenging for older drivers in video sequences used in the clinical study. Central to our appr...
