We propose a novel method for constructing illusory foreground and background shapes
from convex corners. We first introduce a new class of visual cues called corner bases …

Illusory contours occur in a wide variety of circumstances in nature. A striking man-made
example is the Kanizsa triangle. A common factor in all such figures is the perception of a …

Illusory contours, such as the classical Kanizsa triangle and square [9], are intrinsic
phenomena in human vision. These contours are not completely defined by real object …

Much research over the last decade has examined how the brain links local activity within
primary visual cortex to signal the presence of extended global structure. Here we bring …

This paper presents a computational model to recover the most likely interpretation of the 3D
scene structure from a planar image, where some objects may occlude others. The …

We describe how inflation, the act of mapping a 2D silhouette to a 3D region, can be applied
in two disparate problems to offer insight and improvement: silhouette part segmentation …

Boundary completion is one of the desired properties of a robust object boundary detection
model, since in real-word images the object boundaries are commonly not fully and clearly …

Neurophysiological studies and computational models of illusory contour formation have
focused on contour orientation as the underlying determinant of illusory contour shape in …

Shapes are continuous objects, even when they are drawn on digital media or composed
using finite number of elements. As such, they defy analytic approach; explicitization of their …

This paper offers computational theory and an algorithmic framework for perceptual
organization of contours bounding opaque occluding surfaces of constant lightness. For any …
