ABSTRACT:
Pattern recognition, for instance optical character recognition, is achieved by forming a skeletal representation (400) of a pattern (300), processing the skeletal diagram (400) to improve representation of curved lines (308) in the pattern (300), representing the processed skeletal diagram (500) by a connectivity matrix (602), and finding a minimum spectral distance between the connectivity matrix (602) and a set of template matrices corresponding to known patterns.
