count_obj — Number of objects in a tuple.
The operator count_obj determines for the object parameter Objects the number of objects it contains. In this connection it should be noted that object is not the same as connection component (see connection). For example, the number of objects of one region consisting of three parts that are not connected is 1.
For a short description of the iconic objects that are available in HALCON see the introduction of chapter Object.
