[question] Is there such functionality as face tracking?

[odahcam]

I would like to detect emotions from multiple people while still know what people has each emotion in each frame, like:

• 1st frame: person #1 is happy, person #2 is sad, person #3 is happy
• 2nd frame: person #1 is happy, person #2 is happy, person #3 is angry
• 3rd frame: person #1 is happy, person #2 is sad, person #3 is angry

... and beyond, always keep tracking of which person has which emotion in which frame.

Thanks in advance.
