Hierarchical Estimation of Spatial Properties from Motion

Abstract

Multiresolution matching techniques for motion-induced change lead naturally to a hierarchical refinement of three-dimensional properties such as edge location, surface shape, spatial layout, and motion parameters. A hierarchical representation of these relationships is useful for subsequent analysis of more symbolic properties. Aggregate information about larger sufaces is available at the coarser levels of the hierarchy. This can be used to narmalize values at finer levels so that detailed, local properties are not hidden by grosser effects.
