Abstract

The present invention is a system and method for character recognition using pattern recognition. In one embodiment of the invention, a plurality of representations of a plurality of characters is received by a system. A plurality of cipher labels are assigned to representations in the plurality of representations. The plaintext identity of cipher labels in the plurality of cipher labels is determined using isomorphic pattern recognition. The present invention includes A plaintext isomorphic dictionary containing plaintext words organized by their root isomorphic patterns. Additionally, the present invention includes a Raster-Plaintext Library which contains extensive data on taster letters, and their plaintext identities, from an exhaustive collection of fonts.
