Snakes: Active contour models
TLDR
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.
Scale-Space Filtering

  • 1983
TLDR
Scale-space filtering is a method that describes signals qualitatively, managing the ambiguity of scale in an organized and natural way.
Large steps in cloth simulation
TLDR
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.
Analyzing Oriented Patterns
TLDR
A method for the local estimation of anisotropy and a method for combining the estimates to construct a flow coordinate system are developed.
Scale-space filtering: A new approach to multi-scale description

  • 19 March 1984
TLDR
Scale-space filtering is a method that describes signals qualitatively, managing the ambiguity of scale in an organized and natural way.
Uniqueness of the Gaussian Kernel for Scale-Space Filtering
TLDR
It is shown that the Gaussian probability density function is the only kernel in a broad class for which first-order maxima and minima, respectively, increase and decrease when the bandwidth of the filter is increased.
Spacetime constraints
TLDR
This work presents as examples a Luxo lamp performing a variety of coordinated motions that conform to such principles of traditional animation as anticipation, squash-and-stretch, follow-through, and timing.
Using particles to sample and control implicit surfaces
TLDR
By varying the radius of repulsion adaptively, and fissioning or killing particles based on the local density, this work can achieve good sampling distributions very rapidly, and maintain them even in the face of rapid and extreme deformations and changes in surface topology.
Through-the-lens camera control
TLDR
Through-the-lens camera control, a body of techniques that permit a user to manipulate a virtual camera by controlling and constraining features in the image seen through its lens, is introduced.
Variational surface modeling
TLDR
A new approach to interactive modeling of freeform surfaces that is that of an infinitely malleable surface, with no fixed controls, based on a surface representation scheme allowing nonuniform subdivision of B-spline surfaces.
