LBF model in opencv.js not working

maybe you’re out of luck here.
from js, you can only use functions from the whitelist here

and there is no face module (which also would require contrib modules)

you can try to edit the whitelist, add some modules / classes, wrangle the cmake options, and build it from src
(well, good luck, imo that’s difficult)

[edit] can you please explain, what you want to do with it ?
maybe we can find some alternative dnn for this ,…
