6.6.2 What Is Binary Edge?
Binary Edge:
Binary Edge is a function of detecting the boundaries (edges) between white and black or between the
pixels in extract color and the pixels in not extract color and outputting the coordinate values. If the edge
can be detected, it will be judged "OK"; otherwise, it will be judged "NG".
