Description

write_class_train_datawrite_class_train_dataWriteClassTrainDataWriteClassTrainDatawrite_class_train_data writes the training data for classifiers ClassTrainDataHandleClassTrainDataHandleClassTrainDataHandleclassTrainDataHandleclass_train_data_handle to the file given by FileNameFileNameFileNamefileNamefile_name. The classifier can be read again with read_class_train_dataread_class_train_dataReadClassTrainDataReadClassTrainDataread_class_train_data. The default HALCON file extension for the training data is 'ctd'.

Execution Information

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