Perceptual grouping without awareness: superiority of Kanizsa triangle in breaking interocular suppression. [PDF]
PLoS ONE, 2012 Much information could be processed unconsciously. However, there is no direct evidence on whether perceptual grouping could occur without awareness. To answer this question, we investigated whether a Kanizsa triangle (an example of perceptual grouping ...

Cortical algorithms for perceptual grouping
Frontiers in Computational Neuroscience, 2006 A fundamental task of vision is to group the image elements that belong to one object and to segregate them from other objects and the background. This review provides a conceptual framework of how perceptual grouping may be implemented in the visual cortex.

How visual perceptual grouping influences foot placement [PDF]
Royal Society Open Science, 2015 Everybody would agree that vision guides locomotion; but how does vision influence choice when there are different solutions for possible foot placement?

MSLNet and Perceptual Grouping for Guidewire Segmentation and Localization [PDF]
SensorsFluoroscopy (real-time X-ray) images are used for monitoring minimally invasive coronary angioplasty operations such as stent placement. During these operations, a thin wire called a guidewire is used to guide different tools, such as a stent or a ...

Reification through perceptual grouping
2012 12th IEEE-RAS International Conference on Humanoid Robots (Humanoids 2012), 2012 When humans perceive incomplete or ambiguous informations, they tend to instantaneously resolve them by creating meaningful completions. In psychological terms, this generative aspect of perception is called reification. In this paper, we present an approach to model reification by means of perceptual grouping. This technique plays an important role in

Brain networks supporting perceptual grouping and contour selection [PDF]
Frontiers in Psychology, 2014 The human visual system groups local elements into global objects seemingly without effort. Using a contour integration task and EEG source level analyses, we tested the hypothesis that perceptual grouping requires a top-down selection, rather than a ...

A symmetry-based mechanism for perceptual grouping in preverbal infants [PDF]
Scientific ReportsNewborn chicks can solve complex numerical discriminations through a purely perceptual mechanism based on the possibility of creating all equal-sized subsets.

Universal Sketch Perceptual Grouping [PDF]
, 2018 In this work we aim to develop a universal sketch grouper. That is, a grouper that can be applied to sketches of any category in any domain to group constituent strokes/segments into semantically meaningful object parts. The first obstacle to this goal is the lack of large-scale datasets with grouping annotation.

Perceptual Grouping for War and Peace.
, 2022 In a ground war, achieving peace is challenging even when both sides suffer. Here we demonstrate that when humans jointly viewed a battlefield as perceptually grouped by colors, a factor irrelevant to the rules of land-war games, they waged fewer wars and accumulated more wealth due to the perceptual border’s constraint on their aggression.

Time Course of Perceptual Grouping by Color
Psychological Science, 2003 Does perceptual grouping operate early or late in visual processing? One position is that the elements in perceptual layouts are grouped early in vision, by properties of the retinal image, before perceptual constancies have been determined. A second position is that perceptual grouping operates on a postconstancy representation, one that is available
