Comment 35 for bug 507511

I do agree this could be a great addition to digikam software.
Currently, iPhoto and Picasa (web) are doing this.

- Go or you picasa web album and click on "Person" tab.
- all faces are detected (I suspect a script is run periodically to update the cache).
- you access to a serie of batch of photo of the same person and you just enter his/her name.

I would suggest, for this feature to be as killing as possible:
- First, perform a face detection on each photo in the entier library or a smaller part. Then, sort and display first the photos on the person on the most shots. This is psychologically important and have a strong impact since the user will think "whow! it is able to find all the photo with my mum, whoaa!!!". There is also lot of single photo (faces too different), but displayed last it have less impact and this can be entered latter
- of course if the scan already have been performed, the result should be cached/saved somewhere so we don't have to perform a new scan each time.
- In each batch of photo, ask to enter his/her name and tag the photo accordingly (please, use metadata tag written in the file itself, accordingly to a rule like "Persons/Name of the person")
- When adding photo, automatically performs face detection and display the most relevant name, or allow to enter his/her name
