Abstract
An apparatus and method for optical recognition of chemical graphics allows documents containing chemical structures to be optically scanned so that both the text and the chemical structures are recognized. The structures are converted directly into molecular structure files suitable for direct input into chemical databases, molecular modeling programs, image rendering programs and programs that perform real time manipulation of structures.
