چکیده

An oscillatory correlation model of human motion perception is proposed based on the integration of motion and luminance information. The model is composed of two parallel pathways that segment the input scene based on motion and luminance, respectively. Combining these segmentations, the model re nes the motion estimates in the integration stage to obtain the nal segmentation in the motion pathway. For segmentation, LEGION (Locally Excitatory Globally Inhibitory Oscillator Networks) is employed whereby the phases of oscillators are used for region labeling. The model performance is demonstrated using a set of psychophysical data.

An oscillatory correlation model of visual motion analysis.

We describe and evaluate a model of motion perception based on the integration of information from two parallel pathways: a motion pathway and a luminance pathway. The motion pathway has two stages. The first stage measures and pools local motion across the input animation sequence and assigns reliability indices to these pooled measurements. The second stage groups locations on the basis of th...

A Neurocomputational Model of Figure-Ground Discrimination by Relative Motion

A neurocomputational model is presented for gure-ground discrimination by relative motion. In the model, the correlation type of elementary motion detectors (EMDs), an oscillatory neural network for motion perception and a selective attention module are involved. It is shown that through the oscillatory amplitude and frequency encoding and selective synchronization of phase oscillators, a perfe...

Differential Cortical Oscillatory Patterns in Amputees with and Without Phantom Limb Pain

Objective: Phantom limb pain (PLP) as neuropathic pain affects the life of amputees. It is believed an efficient PLP treatment should consider the underlying neurological mechanisms. Hereby, we investigated brain activity in PLP’s and relations to the psychological and cognitive dimension of chronic pain. We investigate differences in resting brain activities between amputees with and without p...
