Claim One:
1. A system, comprising: a processor configured to: extract a subimage from a received image comprising information pertaining to a plurality of numerical characters, wherein the extracted subimage is associated with one of the plurality of numerical characters; perform recognition based at least in part on a set of topological information associated with the subimage, including: process the subimage to obtain the set of topological information associated with the subimage, wherein the processing of the subimage includes: obtain the set of topological information by extracting one or more vertices and one or more edges associated with the subimage; determine whether a closed ring associated with at least a portion of the one or more vertices and at least a portion of the one or more edges exists; and in the event that the closed ring exists, add a location of a point representing the closed ring to the set of topological information; compare the set of topological information associated with the subimage with a preset set of stored topological information; determine that in the event that the set of topological information associated with the subimage matches the preset set of stored topological information, the subimage is associated with a recognized numerical character associated with the preset set of stored topological information; and a memory coupled to the processor and configured to provide the processor with instructions.
