Description

read_ocr_trainf_names_protectedread_ocr_trainf_names_protectedReadOcrTrainfNamesProtectedReadOcrTrainfNamesProtectedread_ocr_trainf_names_protected extracts the names and frequency of all characters in the specified training files. Its functionality corresponds to the functionality of read_ocr_trainf_namesread_ocr_trainf_namesReadOcrTrainfNamesReadOcrTrainfNamesread_ocr_trainf_names, with the addition that read_ocr_trainf_names_protectedread_ocr_trainf_names_protectedReadOcrTrainfNamesProtectedReadOcrTrainfNamesProtectedread_ocr_trainf_names_protected can process unprotected and protected training files. Protected training files can be used only with the correct user password PasswordPasswordPasswordpasswordpassword. If the number of passwords PasswordPasswordPasswordpasswordpassword equals 1, then every input file TrainingFileTrainingFileTrainingFiletrainingFiletraining_file is checked with that password, otherwise the number of passwords has to be equal to the number of input files and the input file at position n is checked with the password at position n. For unprotected training files the passwords are ignored.

For a more detailed description of the operator's functionality see read_ocr_trainf_namesread_ocr_trainf_namesReadOcrTrainfNamesReadOcrTrainfNamesread_ocr_trainf_names. The concept of protecting OCR training data in HALCON is described in protect_ocr_trainfprotect_ocr_trainfProtectOcrTrainfProtectOcrTrainfprotect_ocr_trainf.

Execution Information

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

Parameters

TrainingFileTrainingFileTrainingFiletrainingFiletraining_file (input_control)  filename.read(-array) → HTupleMaybeSequence[str]HTupleHtuple (string) (string) (HString) (char*)

Names of the training files.

Default: '' "" "" "" ""

File extension: .trf, .otr

PasswordPasswordPasswordpasswordpassword (input_control)  string(-array) → HTupleMaybeSequence[str]HTupleHtuple (string) (string) (HString) (char*)

Passwords for protected training files.

CharacterNamesCharacterNamesCharacterNamescharacterNamescharacter_names (output_control)  string(-array) → HTupleSequence[str]HTupleHtuple (string) (string) (HString) (char*)

Names of the read characters.

CharacterCountCharacterCountCharacterCountcharacterCountcharacter_count (output_control)  integer(-array) → HTupleSequence[int]HTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Number of characters.

Result

If the parameter values are correct the operator read_ocr_trainf_names_protectedread_ocr_trainf_names_protectedReadOcrTrainfNamesProtectedReadOcrTrainfNamesProtectedread_ocr_trainf_names_protected returns the value 2 ( H_MSG_TRUE) . Otherwise an exception is raised.
