I construct examples to show that unawareness is distinctly different from assigning zer...

The medial-axis transform, also called skeleton, is a shape abstraction proposed by computer vision. The concept is closely related to cyclographic maps, a tool developed by descriptive geometry to investigate distance functions, and to the solu tion of the eikonal equation. We discuss these connections and their implications on techniques for computing the skeleton.
