[Digikam-users] Face detection / recognition for digikam

Hi Christian,

I think this is a very cool idea.
Could you please file a B.K.O. entry for this wish
(I would be surprised if this does not get many votes quickly ;-).

To try things out like this, the following approach might be possible
from an external script (digikam not running to have no problems
with the database)
- specify a folder for automatic tagging
- run over all images
- for each recognized tag, add this (if not yet present)
  to the database by the usual sql commands

BTW, how good are tools like this today, are they
able to recognize, rivers, lakes, sea, beach, sun, snow, flowers,
birds, ... (just for some of the typical tags ...)?
For birds an automatic recognition of the species would be
helpful (but maybe this is wishing too much ;-)

Best, Arnd

Tags help here, but not all photos are tagged through the reason above. What I would like to see is a plugin that automatically detects faces and allows one to drag a tag from the tag tree on, or just add a tag to the detected face.
