Not really much to add to the question itself.
It is quite established that neurotypical humans are particularly good at DETECTING* faces. Of course there are false positives, i.e. we sometimes see faces where there are none, in the so-called paraeidolieae. But these false positives (together with studies on infants) teach us something important, i.e. that the main heuristic for human face detection is finding sme T-shaped contrast.
As far as I know, many machine vision algorithms work in a similar fashion.
Based on this, I expect that sunglasses should NOT dampen face detection. If anything, they can even INCREASE it.
... but is it the case? Any data on that? I'll be glad if you could point me to some references!
Thank you

* DETECTING is different from RECOGNISING or 'READING' faces. It's not about claiming "this face is X's face" or "this face suggests X's mental state (e.g. anger)", but simply "there is some face here"
Hi Marco Viola,
Yes, wearing sunglasses, hats and some other accessories can affect face detection considerably. However, it depends on the method you are using to detect the faces. Here are some articles that report on this situation.

Hope this helps!
Dear Marco Viola ,
Most of us have them, and as facial recognition technology advances the concept of public anonymity will soon be antiquated. Depending on your personal beliefs, you may find this thought either comforting or frightening. But before we take a look at two different approaches to this divide, we must first look at the effect (if any) that glasses have on this type of technology.

I do not know.
However, I've never put up with them (and don't wear them).
