A shape representation technique suitable for tasks that call for recognition of a noisy curve of arbitrary shape at an arbitrary scale or orientation is presented. The method rests on the describing ...

Leaf shape can vary considerably. The most common shapes include oval, truncate, elliptical, lanceolate, and linear. Leaf tips and bases may also be unique, with names based on their shapes.

A model for the shape of optical fiber tapers, formed by stretching a fiber in a heat source of varying length, is presented. Simple assumptions avoid any need for the techniques of fluid mechanics.
