An Approach for Intersubject Analysis of 3D Brain Images Based on Conformal Geometry
Recent advances in imaging technologies, such as Magnetic Resonance Imaging (MRI), Positron Emission Tomography (PET) and Diffusion Tensor Imaging (DTI) have accelerated brain res...

A Lagrangian Half-Quadratic approach to robust estimation and its applications to road scene analysis
We consider the problem of fitting linearly parameterized models, that arises in many computer vision problems such as road scene analysis. Data extracted from images usually cont...

Detecting Stellar Streams in the Halos of Galaxies with Voronoi Tessellations
Galaxy formation models oriented towards a ΛCDM cosmology envision galaxies as being built through the accretion of dwarf galaxies. Such galaxy accretion should appear as tidally...

Smooth Geometry Images
Previous parametric representations of smooth genus-zero surfaces require a collection of abutting patches (e.g. splines, NURBS, recursively subdivided polygons). We introduce a s...

A Perspective on Distortions
A framework for analyzing distortions in non-single viewpoint imaging systems is presented. Such systems possess loci of viewpoints called caustics. In general, perspective (or un...
