Multi-person tracking and identification for robust framing experience

A method comprising:

• acquiring, at a first time, a first image from one or more cameras of an endpoint device (710);
• determining a first set of persons depicted in the first image (720);
• determining an identifier associated with each person in the first set of persons (740);
• adding, to an identification pool, the identifier associated with the each person in the first set of persons (740);
• acquiring, at a second time, a second image from the one or more cameras (755);
• determining a second set of persons depicted in the second image (760);
• detecting a change between the first set of persons depicted in the first image and the second set of persons depicted in the second image (765);
• and
• maintaining an identifier of a person associated with the change in the identification pool at least until an elapsed time since the second time exceeds a first threshold of time (865, 870, 880).

A system comprising:

• a first endpoint device (910) comprising:
• one or more cameras (942);
• a first memory (950) storing first computer-executable instructions;
• and
• a first hardware processor (920) coupled to the one or more cameras (942) and the first memory (950), the first hardware processor (920) configured to execute the first computer-executable instructions to:
• acquire, at a first time, a first image from the one or more cameras (710);
• determine a first set of persons depicted in the first image (720);
• determine an identifier associated with each person in the first set of persons (740);
• add the identifiers associated with the each person in the first set of persons to an identification pool (745);
• set a tracking status for the each person in the first set of persons to active (745);
• acquire, at a second time, a second image from the one or more cameras (755);
• determine a second set of persons depicted in the second image (760);
• detect a change between the first set of persons depicted in the first image and the second set of persons depicted in the second image (765);
• and
• maintain an identifier of a person associated with the change in the identification pool for a duration of time after the change is detected (865, 870, 880).
