Chapter 9: Object Identification by Binary Conversion
9-1 Outline
When there are several objects and their positions are random, the presence or
absence of objects and the size of the objects can be determined.
- The specified pixel area is converted to a binary image. The number of objects,

total size of the white area (the objects) and the area, center of gravity, main axis
angle, fillet diameter, circumference and center of each white area can be
measured.
