Abstract Of The Disclosure A method of searching a matrix of binary data to find search regions in which straight lines may be found, with the straight lines being those which are perpendicular to the original direction of scanning which produced the matrix of binary data; said method comprising the steps: (a) determining a number of search scans to cover a predetermined area of said matrix of binary data; (b) scanning said predetermined area in a direction which is parallel to said original direction of scanning to search for the presence of binary indicia like binary ones along said predetermined number of search scans to generate search results for each of said search scans, with a binary one indicating the presence of data; (c) ANDing the search results of preselected said search scans to generate AND-scans; (d) ORing preselected said AND-scans to generate OR-scans; and (e) using said OR-scans to define said search regions in which to look for said straight lines which are perpendicular to the original direction of scanning.
