Summary: Face Detection colour filtering and using EXIF-data
Platform: Ubuntu Packages
Component: Face Management

Face detection does not work very well it proivides many hits, which "cannot
be" as green leafes, hous and other technical stuff.
Besides, it looks like (no serious research conducted), as the _same_ face once
upright is detected correctly. And, when finding the same face (of the pic!)
but in horizontal/landscape orientation, face recognition will not
These observations bring me to the questions resp. suggestions:
1.) does face recognition works independent from orientation?
2.) what is the relationship of face recognition algorithm to EXIF-
3.) why green leafes can be recognized as "faces"? Does digiKam respect to
Steps to Reproduce:
1. run face detection
2. after this step, you'll get faces, some recognized, some don't, some
upright, some horizontal
Face recozghnition should work independent from orientatuion and should exclude
"erratic" face colours.
