           Summary: Suggestions for improving face recognition
                    performance.
           Product: digikam
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Face Management
        AssignedTo: digikam-devel at kde.org
        ReportedBy: duartix at hotmail.com


Version:           unspecified (using Devel) 
OS:                Linux

Digikam's face recognition performance is reported to be well below Picasa's
implementation.
Since this is a 2 part problem (face detection + face recognition) I would like
to focus on the second one: Recognition.
This is typically a Supervised Machine Learning problem than can benefit a lot
from as many information as it can gather or has already gathered before. One
source is the image itself (and I've read that it uses OpenCV to extract face
characteristics so in this field I have nothing to comment). 
What I would like to suggest is (in case it's not done already) that:
* People already identified on a training set should have their probability
boosted for recognition if the date of the test set is very close (I mean we
know they were there in the shoot)
* People whose photos are in the same folder as the training set (already
identified ones) should have their probability boosted for recognition (because
we already manually organize them that way)
* People who tend to cluster in the training set should have their probability
boosted for recognition (if there is an unidentified person on a picture where
I  already identified my father there is a big chance that it is my mother)
* People whose photos are geographically clustered should have their
probability boosted for recognition if the photo is taken in a close location
(if the picture was taken in my hometown my parents are mre likely to be in it)
