A border between two image regions normally belongs to only one of the regions;
determining which one it belongs to is essential for surface perception and figure-ground …

Both the sudden appearance of an object and sudden changes in existing object features
influence priority in visual search. However, direct comparisons of these influences have not …

It is an exciting time to study visual object perception. Although object perception research
has a long tradition, lately its visibility in cognitive science and neuroscience has greatly …

Abstract PJ Kellman, P. Garrigan, and TF Shipley's (see record 2005-08166-003) theory of 3-
dimensional object interpolation asserts that existing data, as well as logical considerations …

Two phenomena can be observed in the watercolor illusion: illusory color spreading and
figure-ground organization. We performed experiments to determine whether the figure …

The segregation of image parts into foreground and background is an important aspect of
the neural computation of 3D scene perception. To achieve such segregation, the brain …

We investigated the first-order inputs to contour-shape mechanisms using the shape-
frequency after-effect (SFAE), in which adaptation to a sinusoidally modulated contour …

A common surface is a spatial regularity of our terrestrial environment. For instance, we walk
on the common ground surface, lay a variety of objects on the table top, and display our …

The neuronal and computational mechanisms involved in illusory contour formation are
thought to be sensitive to the orientation and magnitude of contrast at luminance …

We studied a novel illusion of tilt inside checkerboards due to the role of contrast polarity in
contour integration. The preference for binding of oriented contours having same contrast …
