Wide-Baseline Image Matching Using Line Signatures
We present a wide-baseline image matching approach based on line segments. Line segments are clustered into local groups according to spatial proximity. Each group is treated as...

A Computational Model for Repeated Pattern Perception Using Frieze and Wallpaper Groups
Humans have an innate ability to perceive symmetry, but it is not obvious how to automate this powerful insight. In this paper the mathematical theory of Frieze and wallpaper grou...

Energy-based 6-DOF penetration depth computation for penalty-based haptic rendering algorithms
Abstract— Existing penalty-based haptic rendering approaches compute penetration depth in strictly translational sense and cannot properly take object rotation into account. We a...

Improving local learning for object categorization by exploring the effects of ranking
Local learning for classification is useful in dealing with various vision problems. One key factor for such approaches to be effective is to find good neighbors for the learning ...

A Note on Principal Point Estimability
We provide elementary geometric arguments to show that the principal point of cameras with small to moderate field of view cannot be reliably estimated from natural, noisy images ...
