Investigating shape perception by classification images
I Kurki, J Saarinen, A Hyvärinen - Journal of vision, 2014 - jov.arvojournals.org
Radial frequency (RF) patterns are circular contours where the radius is modulated
sinusoidally. These stimuli can represent a wide range of common shapes and have been …

[HTML][HTML] Global shape processing involves feature-selective and feature-agnostic coding mechanisms
J Bell, M Forsyth, DR Badcock - Journal of Vision, 2014 - tvst.arvojournals.org
Recent research and modeling proposes that a closed shape is accurately described by
both the curvature and angular location of its parts relative to the shape center, implying that …

[HTML][HTML] Aging and the integration of orientation and position in shape perception
The current experiments examined the effect of healthy aging on the integration of
orientation and position information in shape perception. Following Day and Loffler (2009) …

Contour inflections are adaptable features
J Bell, S Sampasivam, DP McGovern… - Journal of …, 2014 - jov.arvojournals.org
An object's shape is a strong cue for visual recognition. Most models of shape coding
emphasize the role of oriented lines and curves for coding an object's shape. Yet inflection …

Perceptual binding of static and dynamic signals: a psychophysical and electrophysiological study on contour integration.
R Bellacosa Marotti - 2014 - research.unipd.it
The present work investigates the mechanisms underpinning the integration of local signals
(either local orientations, positions or directions) into whole configurations. The investigation …
