Description

The operator write_ocr_trainf_imagewrite_ocr_trainf_imagewrite_ocr_trainf_imageWriteOcrTrainfImageWriteOcrTrainfImage is used to prepare the training with the operator trainf_ocr_class_mlptrainf_ocr_class_mlptrainf_ocr_class_mlpTrainfOcrClassMlpTrainfOcrClassMlp, trainf_ocr_class_svmtrainf_ocr_class_svmtrainf_ocr_class_svmTrainfOcrClassSvmTrainfOcrClassSvm, or trainf_ocr_class_boxtrainf_ocr_class_boxtrainf_ocr_class_boxTrainfOcrClassBoxTrainfOcrClassBox. Hereby regions, representing characters, including their gray values (region and pixel) and the corresponding class name will be written into a file. An arbitrary number of regions within one image is supported. For each character (region) in CharacterCharacterCharacterCharactercharacter the corresponding class name must be specified in ClassClassClassClassclassVal. If no file extension is specified in FileNameFileNameFileNameFileNamefileName the extension '.trf' is appended to the file name. In contrast to write_ocr_trainfwrite_ocr_trainfwrite_ocr_trainfWriteOcrTrainfWriteOcrTrainf one image per character is passed. The domain of this image defines the pixels which belong to the character. The file format can be defined by the parameter 'ocr_trainf_version'"ocr_trainf_version""ocr_trainf_version""ocr_trainf_version""ocr_trainf_version" of the operator set_systemset_systemset_systemSetSystemSetSystem.

Parameters

CharacterCharacterCharacterCharactercharacter (input_object)  image(-array) → objectHImageHImageHImageXHobject (byte / uint2)

Characters to be trained.

ClassClassClassClassclassVal (input_control)  string(-array) → HTupleHTupleVARIANTHtuple (string) (string) (char*) (BSTR) (char*)

Class (name) of the characters.

FileNameFileNameFileNameFileNamefileName (input_control)  filename.write → HTupleHTupleVARIANTHtuple (string) (string) (char*) (BSTR) (char*)

Name of the training file.

Default value: 'train_ocr' "train_ocr" "train_ocr" "train_ocr" "train_ocr"

Result

If the parameters are correct, the operator write_ocr_trainf_imagewrite_ocr_trainf_imagewrite_ocr_trainf_imageWriteOcrTrainfImageWriteOcrTrainfImage returns the value 2 (H_MSG_TRUE). Otherwise an exception will be raised.
