Description

read_class_train_dataread_class_train_dataReadClassTrainDataReadClassTrainDataReadClassTrainData reads the saved training data for classifiers from the file FileNameFileNameFileNameFileNamefileName (see write_class_train_datawrite_class_train_dataWriteClassTrainDataWriteClassTrainDataWriteClassTrainData). The default HALCON file extension for training data for a classifier is 'ctd'.

Execution Information

This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.

Parameters

FileNameFileNameFileNameFileNamefileName (input_control)  filename.read → HTupleHTupleHtuple (string) (string) (HString) (char*)

File name of the training data.

File extension: .ctd

Handle of the training data.

Result

read_class_train_dataread_class_train_dataReadClassTrainDataReadClassTrainDataReadClassTrainData returns 2 (H_MSG_TRUE). An exception is raised if it was not possible to open the file FileNameFileNameFileNameFileNamefileName or the file has the wrong format.
