Description

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.
