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

Spacetime constraints
TLDR
We present a physically-based approach to character animation in which coordinated, active motion is created automatically by specifying: What the character has to do, for instance “jump from here to there.” How the motion should be performed. Expand

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

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
