Generating aspect graphs for curved objects

Abstract

The authors present an algorithm for computing the aspect graph of a curved object. The approach used to partition the viewpoint space is to compute boundary viewpoints from the shape descriptions of an object in a CAD database. These computations are formulated from the understanding of visual events and the locations of corresponding viewpoints. Also presented is a study of new visual events for piecewise smooth objects.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
