Research output: Contribution to journalArticlepeer-review


The fundamental problem faced by all vision systems is the ambiguity created by the projection process. An object's projected shape in an image changes dramatically for small changes in the observer's viewpoint. This is the basic difficulty in creating a machine vision system that can respond robustly in an unconstrained 3D environment. Our approach to this problem enables the vision system to actively engage its interpretation of the surroundings using a distributed memory system modeled as visual potentials and made up of characteristic view(point)s (Koenderink and van Doorn, 1979).
