[digiKam-users] face detection with 7.2RC 1st try

[digikam at 911networks.com]

Hi, 

Sorry to butt in. I've been a medium term DK user and so far I've not
used the face recognition. With 7.2, I'm planning to start.

From what's I've read so far, the workflow and understanding it seems
to be the problem.

Is there some write-up on what steps should be done to make it run
well.

In my case, I want/hope to identify 5 people (family) through my
50,000 images over the years.

Thank you
