Abstract

A description is given of a prototype address block finding system which is currently under development. This system is intended to support a wider application of machine vision and robotic technologies for the handling of mail. Monochrome digital images of mail are subjected to a sequence of binarization, clustering, and ranking algorithms which are designed to automatically determine the position, extent, and orientation of the destination address block. The prototype system is implemented on a LISP machine to facilitate the extension of the complexity of feature interpretation on an Expert System. Success rates for the end-to-end process were tested on 40 mail images representing a wide variety of mail characteristics.
