create_lexicon
— Create a lexicon from a tuple of words.
create_lexicon( : : Name, Words : LexiconHandle)
create_lexicon
creates a new lexicon based on a tuple of
Words
. By specifying a unique textual Name
, you
can later refer to the lexicon from syntax expressions like those
used, e.g., by do_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.
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.
