PURPOSE:To pick up at high speed the profile of flat diagram drawn on the diagram only with one dimensional operation, by processing the edge graph unidimensionally and picking up the profile lines. CONSTITUTION:The data of n-1-row, n-row and n+1-row are given to the buffers 1-3. Data are picked up sequentially from n-th row and the 1st column to check whether or not the n-th row m-th column is the edge point. If it is the edge point, the rejection point or starting point is discriminated by the window 4 of 3X3. In case of rejection point, m+1-th row is advanced to rewrite the domain table 10. The rewrite of table 10 is made that the presence of edge point of the priority order determining logic diagram is checked and if the edge points are a plurality, one point is determined by using the priority order determining theory. To the edge point decided, the coordinates are calculated from the present point. The present point is checked for which any point in the domain table 10 is in agreement and the next point is decided with the priority decision theory. |
