With labeling, you can separately and individually handle multiple objects
present in the range designated with the window.
When labeling is executed, the µVision board can determine the area, center of
gravity, main axis angle, filet shape, and periphery length as individual object
features. The filet shape is a circumscribe polygon of the objects.

The periphery length is the sum of pixel counts, which form the outer shape of
the object.
