Toward a Surface Primal Sketch
(1985-04-01)
This paper reports progress toward the development of a representation of significant surface changes in dense depth maps. We call the representation the Surface Primal Sketch by analogy with representation of intensity ...
The Curvature Primal Sketch
(1984-02-01)
In this paper we introduce a novel representation of the significant changes in curvature along the bounding contour of planar shape. We call the representation the curvature primal sketch. We describe an implemented ...
Generating and Generalizing Models of Visual Objects
(1985-07-01)
We report on initial experiments with an implemented learning system whose inputs are images of two-dimensional shapes. The system first builds semantic network descriptions of shapes based on Brady's smoothed local ...
