Characterization of Human Faces under Illumination Variations Using Rank, Integrability, and Symmetry Constraints
Photometric stereo algorithms use a Lambertian reflectance model with a varying albedo field and involve the appearances of only one object. This paper extends photometric stereo a...

Faithful Least-Squares Fitting of Spheres, Cylinders, Cones and Tori for Reliable Segmentation
Abstract. This paper addresses a problem arising in the reverse engineering of solid models from depth-maps. We wish to identify and fit surfaces of known type wherever these are a...

Visualizing morphogenesis and growth by temporal interpolation of surface-based 3D atlases
Image-based 3D atlases have been proven to be very useful in biological and medical research. They serve as spatial reference systems that enable researchers to integrate experime...

Isosurfaces Over Simplicial Partitions of Multiresolution Grids
We provide a simple method that extracts an isosurface that is manifold and intersection-free from a function over an arbitrary octree. Our method samples the function dual to min...

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...
