Snakes: Active contour models
TLDR
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

Large steps in cloth simulation
TLDR
The bottle-neck in most cloth simulation systems is that time steps must be small to avoid numerical instability. Expand

Scale-Space Filtering
TLDR
Scale-space filtering is a method that describes signals qualitatively, managing the ambiguity of scale in an organized and natural way. Expand

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. Expand

Scale-space filtering: A new approach to multi-scale description

Uniqueness of the Gaussian Kernel for Scale-Space Filtering
TLDR
Scale-space filtering constructs hierarchic symbolic signal descriptions by transforming the signal into a continuum of versions of the original signal convolved with a kernal containing a scale or bandwidth parameter. Expand

Using particles to sample and control implicit surfaces
TLDR
We present a particle-based approach to sampling and controlling implicit surfaces. Expand

Through-the-lens camera control
TLDR
We introduce 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. Expand
