Abstract

PURPOSE: To enable to detect the edge, by using the original graphic information as it is without processing fine line for the scanned information, through the characteristic pick up of the graph of recognized objective based on the scanning information and the production of edge point representatives.
CONSTITUTION: The characteristic pick up is made based on the scanning information obtained through scanning of the graph for recognition objective 1 and the recognition processing for the graph 1 is made. When the graph 1 is scanned with the horizontal scanning line 3 and the vertical scanning line 14, edge point representatives 10 to 13 are set at the two intermediate positions having each stroke width on the horizontal scanning line 3 including the openings 6 and 7 of the first regions 4 and 5 surrounded with the graphic stroke intersecting toward horizontal scanning direction. Further, on the vertical scanning line including the opening 16 of the second region 15 surrounded with two graphic strokes intersecting vertical direction, edge representatives 18 and 19 are set at the intermediate position having each stroke width, and detection is made by not taking the edge representatives of the overlap regions 20 and 21 where the regions 4, 5 and 15 are superimposed each other but remaining edge representatives.
