Abstract

A system for recognizing and locating printed data of a known spatial characteristic in an image is described. A digital matched filter is used to identify the presence of the printed data via an auto correlation between the filter coefficients and the printed data. When an auto correlation is identified, approximate areas are selected and further processing is undertaken only within such areas.
