Abstract
A character recognition method comprising the steps of (1) acquiring a two dimensional array of pixels, (2) locating a character, (3) determining the size of the character, (4) reducing the number of pixels associated with the character by scaling it down to a smaller dot matrix and (5) thresholding the matrix dots using a histogram to form a binary character representation.
