When does grouping happen? [PDF]
, 2003 Recent research on perceptual grouping is described with particular emphasis on identifying the level(s) at which grouping factors operate. Contrary to the classical view of grouping as an early, two-dimensional, image-based process, recent experimental ...

On the automation of gestalt perception in remotely sensed data [PDF]
Компьютерная оптика, 2018 Gestalt perception, the laws of seeing, and perceptual grouping is rarely addressed in the context of remotely sensed imagery. The paper at hand reviews the corresponding state as well in machine vision as in remote sensing, in particular concerning ...

Editorial: Perceptual Grouping-The State of The Art. [PDF]
Front Psychol, 2017 Perceptual neuroscience has identified mechanisms of perceptual grouping which account for the ways in which visual sensitivity to ordered structure and regularities expresses itself, in behavior and in the brain. The need to actively construct order, notably representations of objects in depth, is mandated as soon as visual signals reach the retina ...

Visual attention and perceptual grouping [PDF]
Perception & Psychophysics, 1992 Perceptual organization is thought to involve an analysis of both textural discontinuities and perceptual grouping. In earlier work, we found that textural discontinuities were detected normally even when visual attention was engaged elsewhere. Here we report how perceptual grouping is affected when visual attention is engaged by a concurrent visual ...

Perceptual grouping in change detection [PDF]
Perception & Psychophysics, 2004 Detection of an item's changing of its location from one instance to another is typically unaffected by changes in the shape or color of contextual items. However, we demonstrate here that such location change detection is severely impaired if the elongated axes of contextual items change orientation, even though individual locations remain constant ...

Disambiguating multi-modal scene representations using perceptual grouping constraints. [PDF]
PLoS ONE, 2010 In its early stages, the visual system suffers from a lot of ambiguity and noise that severely limits the performance of early vision algorithms. This article presents feedback mechanisms between early visual processes, such as perceptual grouping ...

Crossing the midline: reducing attentional deficits via interhemispheric interactions [PDF]
, 2005 Patients with unilateral neglect and extinction show a profound lack of awareness of stimuli presented contralateral to their lesion. However, many processes of perception are intact and contralesional stimuli seem to reach a high level of representation,

Interaction of perceptual grouping and crossmodal temporal capture in tactile apparent-motion [PDF]
, 2011 Previous studies have shown that in tasks requiring participants to report the direction of apparent motion, task-irrelevant mono-beeps can "capture'' visual motion perception when the beeps occur temporally close to the visual stimuli. However, the

Neural correlates of local parallelism during naturalistic vision
PLoS ONE, 2022 Human observers can rapidly perceive complex real-world scenes. Grouping visual elements into meaningful units is an integral part of this process.
