Paper Abstract

A binary facsimile coding technique capable of coding documents at compression ratios from 10:1 to 40:1 has been developed. In the basic system, individual document characters are isolated into small rectangular blocks. The location, size, and contents of each block are coded for transmission. A more sophisticated version of the coder utilizes matching of a character with previously scanned characters. If a match exists, a code word indicating the match is coded along with the character location.
