A REGIONAL DECOMPOSITION METHOD FOR RECOGNIZING HANDPRINTED CHARACTERS

A regional decomposition method is proposed to facilitate pattern anal ysis and recognition. It splits a complicated pattern into several sim ple parts or sub-patterns, so that the pattern can be identified by ex amining the distinct parts. A complexity analysis is derived in this p aper to prove the effectiveness of the regional decomposition method; mathematical and statistical formulas are also provided to evaluate th e recognition rates of different parts. For a sample of 36 alphanumeri c characters handprinted in 89 most common styles, the total mean reco gnition rates of parts have been found to be 30% higher than those obt ained from subjective experiments.
