Snakes: Active contour models
A snake is an energy-minimizing spline guided by external constraint forces and influenced by image forces that pull it toward features such as lines and edges. Expand
Multilinear Analysis of Image Ensembles: TensorFaces
Multilinear algebra, the algebra of higher-order tensors, offers a potent mathematical framework for analyzing the multifactor structure of image ensembles and for addressing the difficult problem of disentangling the constituent factors or modes. Expand
Elastically deformable models
We employ elasticity theory to construct differential equations that model the behavior of non-rigid curves, surfaces, and solids as a function of time. Expand
Deformable models in medical image analysis: a survey
This article surveys deformable models, a promising and vigorously researched computer-assisted medical image analysis technique that combines geometry, physics and approximation theory. Expand
The Computation of Visible-Surface Representations
A computational theory of visible-surface representations is developed. The visible-surface reconstruction process that computes these quantitative representations unifies formal solutions to the keyExpand
Analysis and Synthesis of Facial Image Sequences Using Physical and Anatomical Models
An approach to the analysis of dynamic facial images for the purposes of estimating and resynthesizing dynamic facial expressions from video sequences of expressive human faces is presented. Expand
T-snakes: Topology adaptive snakes
We present a new class of deformable contours (snakes) and apply them to the segmentation of medical images. Expand

  • 1 June 1986
Inverse problems, such as the reconstruction problems that arise in early vision, tend to be mathematically ill-posed. Expand
Realistic modeling for facial animation
We develop algorithms that automatically construct functional models of the heads of human subjects from laser-scanned range and reflectance data. Expand
Dynamic 3D models with local and global deformations: deformable superquadrics
A physically-based approach is presented to fitting complex 3D shapes using a novel class of dynamic models which incorporate the global shape parameters of a conventional superellipsoid with the local degrees of freedom of a spline. Expand
