Automated 3-D Extraction of Inner and Outer Surfaces of Cerebral Cortex from MRI
- NEUROIMAGE
, 2000
"... Automatic computer processing of large multidimensional images such as those produced by magnetic resonance imaging (MRI) is greatly aided by deformable models, which are used to extract, identify, and quantify specific neuroanatomic structures. A general method of deforming polyhedra is presented h ..."

here, with two novel features. First, explicit prevention of self-intersecting surface geometries is provided, unlike conventional deformable models, which use regularization constraints to discourage but not necessarily prevent such behavior. Second, deformation of multiple surfaces with intersurface
Pointshop 3D: An Interactive System for Point-Based Surface Editing
, 2002
"... We present a system for interactive shape and appearance editing of 3D point-sampled geometry. By generalizing conventional 2D pixel editors, our system supports a great variety of different interaction techniques to alter shape and appearance of 3D point models, including cleaning, texturing, sculp ..."

A level-set approach to 3d reconstruction from range data
- International Journal of Computer Vision
, 1998
"... This paper presents a method that uses the level sets of volumes to reconstruct the shapes of 3D objects from range data. The strategy is to formulate 3D reconstruction as a statistical problem: find that surface which is mostly likely, given the data and some prior knowledge about the application d ..."

domain. The resulting optimization problem is solved by an incremental process of deformation. We represent a deformable surface as the level set of a discretely sampled scalar function of 3 dimensions, i.e. a volume. Such level-set models have been shown to mimic conventional deformable surface models
Automatically parcellating the human cerebral cortex.

Abstract -We present a technique for automatically assigning a neuroanatomical label to each location on a cortical surface model based on probabilistic information estimated from Introduction Techniques for labeling geometric features of the cerebral cortex are useful for analyzing a variety of fu ..."

A unifying theory for central panoramic systems and practical implications
- In ECCV
, 2000
"... Abstract. Omnidirectional vision systems can provide panoramic alertness in surveillance, improve navigational capabilities, and produce panoramic images for multimedia. Catadioptric realizations of omnidirectional vision combine reflective surfaces and lenses. A particular class of them, the centra ..."

Design of ion-implanted MOSFETs with very small physical dimensions
- IEEE J. Solid-State Circuits
, 1974
"... This paper considers the design, fabrication, and characterization of very small MOSFET switching devices suitable for digital integrated circuits using dimensions of the order of 1. Scaling relationships are presented which show how a conventional MOS-FET can be reduced in size. An improved small d ..."

Object-Centered Surface Reconstruction: Combining Multi-Image Stereo and Shading
- International Journal of Computer Vision
, 1995
"... Our goal is to reconstruct both the shape and reflectance properties of surfaces from multiple images. We argue that an object-centered representation is most appropriate for this purpose because it naturally accommodates multiple sources of data, multiple images (including motion sequences of a rig ..."

The method begins with an initial estimate of surface shape provided, for example, by triangulating the result of conventional stereo. The surface shape and reflectance properties
Linear Models of Surface and Illuminant Spectra
- J. OPT. SOC. AM. A
, 1992
"... We describe procedures for creating efficient spectral representations for color. The representations generalize conventional tristimulus representations, which are based on the peripheral encoding by the human eye. We use low-dimensional linear models to approximate the spectral properties of surfa ..."

Helmholtz Stereopsis: Exploiting Reciprocity for Surface Reconstruction
"... We present a method – termed Helmholtz stereopsis – for reconstructing the geometry of objects from a collection of images. Unlike existing methods for surface reconstruction (e.g., stereo vision, structure from motion, photometric stereopsis), Helmholtz stereopsis makes no assumptions about the nat ..."

Multi-Projector Displays Using Camera-Based Registration

While this results in rendering simplicity and speed, it also means painstaking construction and ongoing maintenance. In previously published work, we int ..."
