1. An optical character recognition system for recognizing each character of a text, comprising:

  • means for (a) determining the position of each line of characters of the text, (b) scanning each line of text by scanning said text in successive frames of a predetermined height and width independent of the script and language of said text, and (c) generating data representing all of the optically scanned characters of the text as a function of a single independent variable in one direction, said variable being a function of a feature vector representing a plurality of elements, each element being a function of the percentile height below which a prespecified percentage of black pixels lies;

    means for providing a probabilistic paradigm so as to determine each of said characters of said text from said data.
