Abstract
A method and system of recognizing a string of characters in a target image. An acquired target image is analyzed using an optical character recognition process to identify a candidate string, the candidate string having an associated plurality of character positions, each character position being associated with a set of one or more candidate characters located at related positions in the target image. A minimum edit cost is determined between the candidate string and a template for an output string. Determining the minimum edit cost includes, for a given character position in the candidate string and a given output character position in the template, identifying, among the respective set of candidate characters of the candidate string, a subset of candidate characters that satisfy the respective character set of the template; and determining an edit cost based on the recognition score of one of the candidate characters belonging to the identified subset of candidate characters. An output string corresponding to the determined minimum edit cost is returned.
