Description nathmo 2021-08-22 16:19:36 UTC 
SUMMARY
sometimes the program draw two bounding boxes around the same face. it tag them correctly twice as they both belong to the same person.

STEPS TO REPRODUCE
1. Find a picture with a face that have that problem (see attachment)
2. run the face automatic detection + tagging

OBSERVED RESULT
two bounding box overlap on the same face.

EXPECTED RESULT
Reject one of the overlapping bonding box when belonging to the same person.

GNOME Version: 3.36.8 
KDE Frameworks Version: 
Qt Version: 

ADDITIONAL INFORMATION
I believe this a minor bug with a possibly simple work around of preventing box overlapping when of the same person that can slighty enhance the accuracy.

you might need the state of face recognition engine and I am not sure i included the right file but i will gladly try to attach the right one if needed and instruction are provided.
