[digiKam-users] --> Tunning Face Recgnition

[marcpalaus at hotmail.com]

I remember there is a slider to adjust the sensitivity/specificity (more 
false positives/more false negatives) in the detection. But that won't 
improve the recognition by much (settings between 60 and 80 worked best 
for me). The fact is that the recognition only works well under certain 
conditions (a group of well defined faces looking to the camera, and 
without too many people to choose from). It seems that it will be 
improved during this summer as one of the projects for the Google Summer 
of Code 2020, so if it goes well, we may see the results by the end of 
the year.

Oh, and it's a know issue. If you delete a face rectangle, and run the 
detection again, it will be detected once again. There's a feature under 
development (again, summer of code) which will add an "Ignored" category 
that would solve this.

So I am optimist that in the future both issues will improve.
