This invention relates to a facsimile compression method for minimizing the number of mismatches between scanned characters and a reduced number of templates. The method steps comprise: (1) buffering a page of characters; (2) scanning the page and assigning scan characters into similarity classes; (3) constructing the best matched prototype for members of each class; and (4) transmitting a number indicative of a match between each character occurrence and one of the set of prototypes.
