Abstract

Banking apparatus for high speed processing of bank checks, drafts and like documents having numeric characters in courtesy amount fields. The documents are conveyed along a path and the courtesy amount field with the numeric character are located, scanned, digitized and the numeric characters are supplied to a plurality of parallel connected artificial fovea, each artificial fovea including temporary storage and image section measurement circuits. Recognition scoring circuits identify the numeric characters from the respective artificial fovea.

Claims

1. Banking apparatus for high speed processing bank checks, drafts and like documents having courtesy amount fields thereon with numeric characters therein, comprising:

means for conveying said documents along a path,

means for locating and scanning said courtesy amount field to produce an optical image thereof,

digitizing means for converting said optical image of the numeric character in said courtesy amount field to an electronic binary black/white pixel image thereof,

a plurality of parallel connected artificial fovea for emulating the behavior of a human fovea, each artificial fovea including means for temporary storage of said pixel image, means for measuring sections of said pixel images to produce image measurements, means for scoring said image measurements, and

recognition scoring means having recognition equations stored therein, said recognition scoring means being connected to said plurality of artificial fovea to score the image measurements from each said artificial fovea and identify the numeric character from the respective artificial fovea.

2. The banking apparatus as defined in claim 1 wherein said means for measuring in each said artificial fovea includes means for examining each pixel in said black/white pixel image to locate one or more centers of recognition pixels,

means for determining the boundedness of other pixels having a specific relationship to said center of recognition pixel, and producing said image measurements to recognize said numeric characters.

3. The banking apparatus defined in claim 1 including resolution modification means connected between said digitizing means and said plurality of artificial fovea to initially reduce the number of pixels contained in a particular image and if one of said artificial fovea reject a pixel image of a numeric character with reduced resolution, said resolution modification means increases the resolution.
