Symbolic Construction of a 2-D Scale-Space Image
August 1990 (vol. 12 no. 8)
pp. 817-830

A symbolic approach to constructing a multiscale primitive shape description to 2-D binary (silhouette) shape images is presented. In contrast to contour or region smoothing techniques, grouping operations are performed over collections of tokens residing on a scale-space blackboard. Two types of grouping operations are identified that, respectively, aggregate edge primitives at one scale into edge primitives at a coarser scale and group edge primitives into partial-region assertions, including curved contours, primitive corners, and bars. Procedures to perform these computations are presented.
