Optimality of human contour integration. [PDF]
PLoS Computational Biology, 2012 For processing and segmenting visual scenes, the brain is required to combine a multitude of features and sensory channels. It is neither known if these complex tasks involve optimal integration of information, nor according to which objectives ...

Contour integration deficits at high spatial frequencies in children treated for anisometropic amblyopia [PDF]
Frontiers in Neuroscience, 2023 PurposeThis study was conducted to reexamine the question of whether children treated for anisometropic amblyopia have contour integration deficits. To do so, we used psychophysical methods that require global contour processing while minimizing the ...

Contour Integration in Dynamic Scenes: Impaired Detection Performance in Extended Presentations [PDF]
Frontiers in Psychology, 2017 Since scenes in nature are highly dynamic, perception requires an on-going and robust integration of local information into global representations. In vision, contour integration (CI) is one of these tasks, and it is performed by our brain in a seemingly

Context modulates the ERP signature of contour integration. [PDF]
PLoS ONE, 2011 We investigated how the electrophysiological signature of contour integration is changed by the context in which a contour is embedded. Specifically, we manipulated the orientations of Gabor elements surrounding an embedded shape outline.

The role of sensory uncertainty in simple contour integration. [PDF]
PLoS Computational Biology, 2020 Perceptual organization is the process of grouping scene elements into whole entities. A classic example is contour integration, in which separate line segments are perceived as continuous contours.

Effects of Spatial Frequency Similarity and Dissimilarity on Contour Integration. [PDF]
PLoS ONE, 2015 We examined the effects of spatial frequency similarity and dissimilarity on human contour integration under various conditions of uncertainty. Participants performed a temporal 2AFC contour detection task.
