For the sake of simplicity we will refer toall of them using the term object.The parameters of a HALCON operator are numbered consecutively from ½ to Ò (not from ¼to Ò ½) for each parameter class (input/output object/control). The parameter ÔÖ ÒÙÑ ofÀØÇ refers to this number, thus specifying the desired input object parameter. All objectspassed within a single input object parameter are numbered from ½ to Ñ, with the first object inthe list having the number ½. The parameter Ó ÒÙÑ of ÀØÇ denotes the index of a desiredobject within this list (½ Ó ÒÙÑ Ñ).HALCON Extension Package Interface / 2000-11-16
