           Summary: Digikam detects but does not recognize faces.
           Product: digikam
           Version: 2.0.0
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Face Detection
        AssignedTo: digikam-devel at kde.org
        ReportedBy: mrzanda at yahoo.co.uk


Version:           2.0.0 (using KDE 4.6.2) 
OS:                Linux

Digikam does a decent job at detecting faces (which is excellent), but once it
does, it is absolutely incapable of recognizing and sorting them. 

Even after manually tagging a large number of the faces it detected, digikam
cannot automatically tag any of the faces in the "unknown" folder.

Also the processing speed for face recognition is suspiciously fast: the job is
completed in a matter of a few seconds, even though the catalog has many
hundreds faces in it. Just detecting faces takes ages and much computing power
(understandably), but it's strange that face recognition is so much faster (but
non functional!). 

Reproducible: Always

Steps to Reproduce:
open "scan for faces dialog"
select "recognize faces"
click "scan"

Actual Results:  
no faces tagged as "unknown" are recognized, no matter how many times the
people in those images have been tagged already (manually). 

Expected Results:  
"mike's" face tagged as unknown should be automatically tagged as "mike" and
put in the "mike" folder, provided the user already manually tagged "mike"
enough times for the software to "know" his face.

Also it would be helpful it digikam sorted all faces in different tags e.g.
unknown#1, unknown#2, etc, so it would be easier to perform batch tagging.
