Journal ArticleDOI
Snakes : Active Contour Models
TL;DR: This work uses snakes for interactive interpretation, in which user-imposed constraint forces guide the snake near features of interest, and uses scale-space continuation to enlarge the capture region surrounding a feature.
Book ChapterDOI
Scale-space filtering
TL;DR: Scale-space filtering is a method that describes signals qualitatively, managing the ambiguity of scale in an organized and natural way.
Proceedings ArticleDOI
Large steps in cloth simulation
David Baraff,Andrew Witkin +1 more
TL;DR: A cloth simulation system that can stably take large time steps is described, which is significantly faster than previous accounts of cloth simulation systems in the literature.
Proceedings ArticleDOI
Scale-space filtering: A new approach to multi-scale description
TL;DR: Scale-space filtering is a method that describes signals qualitatively, managing the ambiguity of scale in an organized and natural way.
Journal ArticleDOI
Constraints on deformable models: recovering 3D shape and nongrid motion
TL;DR: This work describes an extrinsic force that applies constraints derived from profiles of monocularly viewed objects and generalizes this constraint force to incorporate profile information from multiple views and use it to exploit binocular image data.
