Warning

enquire_class_boxenquire_class_boxEnquireClassBoxEnquireClassBoxenquire_class_box is obsolete and is only provided for reasons of backward compatibility. New applications should use the MLP, SVM, KNN or GMM operators instead. The operator will be removed with HALCON 25.11.

Description

FeatureListFeatureListFeatureListfeatureListfeature_list is a tuple of any floating point- or integer numbers (attributes) which has to be assigned to a class with assistance of a previous trained (learn_class_boxlearn_class_boxLearnClassBoxLearnClassBoxlearn_class_box) classifier. It is possible to specify attributes as unknown by indicating the symbol '*' instead of a number. If you specify n values, then all following values, i.e. the attributes n+1 until 'max', are automatically supposed to be undefined.

See learn_class_boxlearn_class_boxLearnClassBoxLearnClassBoxlearn_class_box for more details about the functionality of the classifier.

You may call the operators learn_class_boxlearn_class_boxLearnClassBoxLearnClassBoxlearn_class_box and enquire_class_boxenquire_class_boxEnquireClassBoxEnquireClassBoxenquire_class_box alternately, so that it is possible to classify already in the phase of learning. This means you could see when a satisfying behavior had been reached.

Execution Information

  • Multithreading type: reentrant (runs in parallel with non-exclusive operators).
  • Multithreading scope: global (may be called from any thread).
  • Processed without parallelization.
