CHARACTER SEGMENTING APPARATUS FOR OPTICAL CHARACTER RECOGNITION

A character segmenting apparatus has an optical scanner for scanning the surface of an article of mail. The scan is in a direction which is substantially perpendicular to the direction of the relative movement between the optical scanner and the mail article. The scan generates a pattern signal which is then recurrsively compressed and updated in the width of a black picture element contained in the pattern signal. A character segmenting signal is produced when no black picture element exists in a portion of the pattern signal, delivered from the optical scanner, which corresponds to the black picture element contained in the compressed pattern signal. Size and position information of a whole segmented character is developed in response to the character segmenting signal.
