ABSTRACT:
Machine encoding of forms allows a simple recognition system to determine what marks on the form bear relevant information and, then to transmit only the relevant information, i.e. transmits bit maps representing the unique parts of the form and a description of the form itself but not a bit map of the entire form. Depending on the architecture of the system and the needs of the user, the original document may be processed at the reception site after only a small fraction of the document' contents has been transmitted. Transmission of bit mapped information is thus proportional only to the size and density of the bit map to be transmitted. Transmission of other types of information, e.g. checkboxes or ASCII coded data, is proportional to the number of such items, and not their size or density.
