Computer pattern recognition of printed music

A major area of concentration of pattern recognition research has been the design of computer programs to recognize two-dimensional visual patterns. These patterns may be divided into two classes: patterns representing objects in the real world (e.g., landscapes, blood cells) and patterns representing conventionalized symbols (e.g., printed text, maps). The standard notation used to specify most instrumental and vocal music forms a conventionalized, two-dimensional, visual pattern class.
