Multigrid Relaxation Methods and the Analysis of Lightness, Shading and Flow
(1984-10-01)
Image analysis problems, posed mathematically as variational principles or as partial differential equations, are amenable to numerical solution by relaxation algorithms that are local, iterative, and often parallel. ...
Multi-Level Reconstruction of Visual Surfaces: Variational Principles and Finite Element Representations
(1982-04-01)
Computational modules early in the human vision system typically generate sparse information about the shapes of visible surfaces in the scene. Moreover, visual processes such as stereopsis can provide such information at ...
