A Personal Surround Environment: Projective Display with Correction for Display Surface Geometry and Extreme Lens Distortion
Projectors equipped with wide-angle lenses can have an advantage over traditional projectors in creating immersive display environments since they can be placed very close to the ...

Spherical Catadioptric Arrays: Construction, Multi-View Geometry, and Calibration
This paper introduces a novel imaging system composed of an array of spherical mirrors and a single highresolution digital camera. We describe the mechanical design and constructi...

Image Reconstruction Using Particle Filters and Multiple Hypotheses Testing
Abstract—In this paper, we introduce a reconstruction framework that explicitly accounts for image geometry when defining the spatial interaction between pixels in the filterin...

The Hyperbolic Geometry of Illumination-Induced Chromaticity Changes
The non-negativity of color signals implies that they span a conical space with a hyperbolic geometry. We use perspective projections to separate intensity from chromaticity, and ...

Can voronoi diagram model cell geometries in early sea-urchin embryogenesis?
We test the hypothesis that cell membranes in early seaurchin embryos can be modeled as a Voronoi diagram from nuclei centers. In order to obtain a model of the cell geometry agai...
