Abstract
A method and apparatus for improving a text image represented as a bitmap in a digital system. Character instances in the bitmap image are recognized and categorized according to their character type. The instances are used to derive a prototype character for each character type. The prototype character is an average of the instances, thus providing for cancellation of extraneous marks in the bitmap image. The prototype character is substituted for each character instance of its type in the bitmap image thus providing for uniformity of characters in a regenerated version of the original bitmap.
