描述
read_ocr_trainf_names_protectedread_ocr_trainf_names_protectedReadOcrTrainfNamesProtectedReadOcrTrainfNamesProtectedReadOcrTrainfNamesProtectedread_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_namesReadOcrTrainfNamesReadOcrTrainfNamesReadOcrTrainfNamesread_ocr_trainf_names,
with the addition that read_ocr_trainf_names_protectedread_ocr_trainf_names_protectedReadOcrTrainfNamesProtectedReadOcrTrainfNamesProtectedReadOcrTrainfNamesProtectedread_ocr_trainf_names_protected
can process unprotected and protected training files. Protected
training files can be used only with the correct user password
PasswordPasswordPasswordPasswordpasswordpassword. If the number of passwords PasswordPasswordPasswordPasswordpasswordpassword
equals 1, then every input file TrainingFileTrainingFileTrainingFileTrainingFiletrainingFiletraining_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.

data in HALCON is described in protect_ocr_trainfprotect_ocr_trainfProtectOcrTrainfProtectOcrTrainfProtectOcrTrainfprotect_ocr_trainf。
