Abstract
A high speed system for locating and decoding glyphs on documents is disclosed. The system includes acquiring one or more images of a document containing a glyph. One-dimensional projections of the images are correlated against a reference function to locate the glyph in the images. The position of the glyph is refined by correlating against a kernel designed to have a maximum response when aligned over a corner of the glyph. Symbols in the glyph are decoded utilizing a kernel which generates a positive response for one symbol type and a negative response for the other.
