Signature
def create_lexicon(name: str, words: Sequence[str]) -> HHandle
Description
create_lexiconcreate_lexiconCreateLexiconCreateLexiconCreateLexiconcreate_lexicon creates a new lexicon based on a tuple of
WordsWordsWordsWordswordswords. By specifying a unique textual NameNameNameNamenamename, you
can later refer to the lexicon from syntax expressions like those
used, e.g., by do_ocr_word_mlpdo_ocr_word_mlpDoOcrWordMlpDoOcrWordMlpDoOcrWordMlpdo_ocr_word_mlp.
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.
