From Boundaries to Bumps: when closed (extremal) contours are critical
Benjamin Kunsberg, Steven W. Zucker
Invariants underlying shape inference are elusive: a variety of shapes can give rise to the same image, and a variety of images can be rendered from the same shape. The occluding c…
What's In A Patch, I: Tensors, Differential Geometry and Statistical Shading Analysis
Daniel Niels Holtmann-Rice, Benjamin S. Kunsberg, Steven W. Zucker
We develop a linear algebraic framework for the shape-from-shading problem, because tensors arise when scalar (e.g. image) and vector (e.g. surface normal) fields are differentiate…
Critical Contours: An Invariant Linking Image Flow with Salient Surface Organization
Benjamin S. Kunsberg, Steven W. Zucker
We exploit a key result from visual psychophysics---that individuals perceive shape qualitatively---to develop the use of a geometrical/topological "invariant'' (the Morse--Smale c…
Tensors, Differential Geometry and Statistical Shading Analysis
Daniel Niels Holtmann-Rice, Benjamin S. Kunsberg, Steven W. Zucker
We develop a linear algebraic framework for the shape-from-shading problem, because tensors arise when scalar (e.g. image) and vector (e.g. surface normal) fields are differentiate…
Characterizing Ambiguity in Light Source Invariant Shape from Shading
Benjamin Kunsberg, Steven W. Zucker
Shape from shading is a classical inverse problem in computer vision. This shape reconstruction problem is inherently ill-defined; it depends on the assumed light source direction.…
Model Cortical Association Fields Account for the Time Course and Dependence on Target Complexity of Human Contour Perception
Vadas Gintautas, Michael I. Ham, Benjamin Kunsberg +7
Can lateral connectivity in the primary visual cortex account for the time dependence and intrinsic task difficulty of human contour detection? To answer this question, we created…
