Does this mean that it is problematic to tag exceptionally blurry faces 
as "ignore" in that this could result in some kind of "catch all face" 
that will match a lot of faces incorrectly?

PS. What about the "This is not a face" (red X button) - does this also 
just tag the detected face region as a "not face" tag? Or does it rather 
just throw the face out of the detected faces pile (thus, resulting in 
this image region being re-detected as a face some later time)? Or how 
does this work?

I have noticed that when I have a picture with high entropy regions like 
a heap of gravel or rocks, it will often detect faces in that "noise". I 
always click "This is not a face" but I have a feeling that the same 
regions keep turning up when I do face detection again. But maybe it is 
just other regions of the same "noise"?
