ABSTRACT:
An optical recognition method and system utilizes a scanner to digitize a complex document comprising regions of text and graphics. A recognition engine, illustratively in the form of a general purpose computer, separates regions of text and graphics and identifies lines of text. Character boundaries are determined in each line of text by forming a shadow of the line of text on the horizontal axis. Each byte from the shadow is utilized to access a table stored in a memory associated with the recognition engine. The value contained in the table provides information as to where boundaries are located in the portion of the line of text corresponding to the byte from the shadow.
