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.

Neuronal oscillations during contour integration of dynamic visual stimuli form parietal/frontal networks [PDF]
Frontiers in Integrative Neuroscience, 2014 The ability to integrate visual features into a global coherent percept that can be further categorized and manipulated are fundamental abilities of the neural system.

Contour integration with corners
Vision Research, 2016 Contour integration refers to the ability of the visual system to bind disjoint local elements into coherent global shapes. In cluttered images containing randomly oriented elements a contour becomes salient when its elements are coaligned with a smooth global trajectory, as described by the Gestalt law of good continuation. Abrupt changes of curvature

Perceptual load modulates contour integration in conscious and unconscious states [PDF]
PeerJ, 2019 Previous research has documented that contour detection and integration may either be affected by local features such as the distances between elements or by high-level cognitive factors such as attention in our visual system. Less is known about how low

Do We Need Another Neural Correlate of Contour Integration? [PDF]
i-Perception, 2014 Gilad and colleagues use an elegant combination of voltage-sensitive dyes and high temporal and spatial resolution optical imaging to visualize a differential response to collinear contour elements in monkey V1.

The effect of aging on contour integration
Vision Research, 2008 Perception of global patterns requires the integration of local orientation information across space. The present study examined whether this integration ability declines in older age. We measured contrast thresholds for discriminating the global orientation of a "C" shaped contour against a blank background in younger and older subjects.

Contour integration in anisometropic amblyopia
Vision Research, 1998 Contour integration was measured in a group of anisometropic amblyopes to test the idea recently put forward that positional uncertainty sets a fundamental limit to contour integration in amblyopia. Anisometropic amblyopia, unlike strabismic amblyopia, has little or no positional uncertainty once the initial filtering loss has been taken into account ...

Closure facilitates contour integration
Vision Research, 2007 Closed contours are often better perceived than those not fully enclosing an area, i.e., open contours. This facilitation of contour integration by closure, however, has been questioned arguing that in earlier studies closed contours were often "smoother" than open ones, because open contours usually had turning points.

Contour integration across depth
Vision Research, 1995 In order to investigate the extent of the local connections subserving contour integration across depth, we measured performance for detecting the continuity of a path of Gabor elements distributed in depth and embedded in a three-dimensional field of random background elements.

Contour integration in the peripheral field
Vision Research, 1999 Contour integration was measured in the normal peripheral field to determine if an explanation based solely on the known peripheral positional uncertainty was sufficient to explain performance. The task involved the detection of paths composed of micropatterns with correlated carrier orientations embedded in a field of similar micropatterns of random ...
