Description

create_lexiconcreate_lexiconCreateLexiconcreate_lexiconCreateLexiconCreateLexicon 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_mlpDoOcrWordMlpdo_ocr_word_mlpDoOcrWordMlpDoOcrWordMlp.

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.

Parallelization

This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.
