1. A method of recognizing alphanumeric characters in an image comprising:

  • computing individual representations of all alphabet characters of an alphabet at every character position within a word transcription length;

    embedding said individual representations of said alphabet characters in a common vectorial subspace using a matrix to produce embedded alphabet characters;

    embedding a received image of an alphanumeric word into said common vectorial subspace using said matrix to produce an embedded alphanumeric character image, said embedded alphanumeric character image representing image characters at character positions;

    computing a utility value of every one of said embedded alphabet characters at each of said character positions with respect to said embedded alphanumeric character image;

    computing a highest-utility transcription alphabet character for every one of said character positions based on said utility value of each said embedded alphabet character at each of said character positions, within said word transcription length; and

    assigning said highest-utility transcription alphabet character for each of said character positions to produce a recognized alphanumeric word within said received image.
