create_lexiconcreate_lexiconCreateLexiconCreateLexiconCreateLexicon creates a new lexicon based on a tuple of WordsWordsWordsWordswords. By specifying a unique textual NameNameNameNamename, you can later refer to the lexicon from syntax expressions like those used, e.g., by do_ocr_word_mlpdo_ocr_word_mlpDoOcrWordMlpDoOcrWordMlpDoOcrWordMlp.

Note that lexicon support in HALCON is currently not aimed at natural languages. Rather, it is intended as a post-processing step in OCR applications that only need to distinguish between a limited set of not more than a few thousand valid words, e.g., country or product names. MVTec itself does not provide any lexica.
