The counting can use the M1-parameter as discriminator.
The M1 is a size independent moment-based feature describing the compactness og the object.
•A perfect round compact object will measure 15
•A “long stripe” will measure 70+
The enable this, check the check box, and set the sliders to the area range to include in the counting.
Example: Only objects with an M1 in the range 15 – 27 will be included in the counting. This will exclude “long” objects.
