Thanks to @adamhrv other models to investigate:

Is there a TF.js version of TinyFaces, RetinaFace, or YoloV4? Less performant, but only 1MB there is also https://github.com/Linzaer/Ultra-Light-Fast-Generic-Face-Detector-1MB that could perhaps be ported to JS?

@shiffman - I suppose if the point is to focus on masking faces, we could/should use a lib specifically for face detection? The Tiny Face model of face-api is actually pretty snappy.

[shiffman]

yes, I was thinking of adding this in as a second pass to catch faces that BodyPix misses. Then we could have an interface with checkboxes for which models you want to run (one or both):

• BodyPix
• TinyFace

And maybe we offer more models that people can try some might work better with different videos.

And also options for:

• Block faces
• Block bodies

So you can choose one or both. . .

That's great + makes perfect sense.

[shiffman]

Great! I am going to work on adding TinyFace in a separate branch, more soon!
