Claim:
1. A computer-implemented method, comprising: receiving an image of a gift card, the gift card containing a plurality of claim code characters; generating a binarized image of the gift card; determining a plurality of character patches of the binarized image; grouping the plurality of character patches into one or more grouped character patches; performing a first close cut of the one or more grouped character patches based at least upon top and bottom positions of the one or more grouped character patches; determining one or more clean-cut regions of the binarized image, wherein the one or more clean-cut regions have a subset of the grouped character patches satisfying a predetermined condition; determining a first range of width for grouped character patches in the first subset; classifying the one or more grouped character patches into a first set of candidate claim code characters according to the one or more machine learning algorithms based at least in part on the one or more clean-cut regions; and identifying the plurality of claim code characters from the first set of candidate claim code characters.
