[Digikam-users] Better explanation of face recognition buttons?

[Roger Mårtensson]

Hi!

Maybe you could explain something for me. Couldn't find it in the Help 
and my Google-fu seem to have deserted me this evening.

I have scanned my collection after faces and ran a recognition run.
It seems a lot more stable and and better in finding and recognizing 
faces. Thank you for your hard work devs. This is a function I'm really 
enjoy having.

Now.. To my question. When walking through all my pictures to tag them 
with names I see some buttons and a textbox.
One of these buttons is labeled (the only one labeled) and that is the 
"Not a face" button on the upper right on the face picture. When pressed 
is the found face stored as a "not a face" or just removed from picture?

The textbox is self explanatory.

Under the textbox we have two buttons. One is a "v" and one is a "-". 
The "v" I guess is the Accept button. I.e. Tag picture with supplied name.
And the "-" means no.. It is a face but not for the guessed name.
Right?

What more happens when I press any of these buttons?
I guess that with "v"-button the picture is tagged with the namd and 
recognized face is stored somewhere?
And what happens when I press "-"-button? Do it store the found face but 
tag it as a unknown and will once again be checked against my faces on 
the next scan (until a recognized face is found)?
That is what I'm guessing but am I right?

To me Unknown means that it is a face I haven't tagged yet and should be 
checked again when recognizing faces. For example. I currently have 285 
found faces of my wife. Not all of these are of my wife and those who 
are not I want to be removed from my wifes Tag-list to be checked once 
again and maybe the next run will maybe get it right. Hopefully the face 
does get stored as "an Unknown but certainly not my wife".

Last question I have is how you do when you have a face that "is a face" 
but it is a face I don't care about. It is of a complete stranger that I 
don't care or want tag. Do you use the "Not a face"-button? Would be 
nice to have a "Is a face but is a stranger"-button. :)
