Patent ID: 7327883

Claim:
A method for translating a written document into a computer-readable document, said method comprising: providing a pixel representation of the written document; providing a vector base comprising a plurality of classes, each said class corresponding to a computer-readable code and comprising a predetermined vector quantization of said corresponding computer-readable code; identifying a field into said pixel representation of the written document; segmenting said field, thereby yielding a segmented symbol; performing a vector quantization on said segmented symbol; comparing said vector quantization of said segmented symbol with said predetermined vector quantization of each said class, thereby assigning a similarity score between said segmented symbol and each said class; and determining if only one of said similarity scores exceeds a predetermined threshold; wherein when only one said similarity score exceeds said predetermined threshold, assigning to said segmented symbol a said computer-readable code corresponding to a said class for which said only one similarity score exceeds said predetermined threshold.
