5. A method comprising:
capturing a thermal image of a human being using a thermal imager;
detecting, using an artificial neural network of a detection system, a face and an inner canthus of the human being in the thermal image;
determining a temperature measurement of the inner canthus using corresponding pixels of the thermal image;
determining a body temperature of the human being using the temperature measurement; and
generating a notification to identify an elevated body temperature in response to the body temperature exceeding a threshold; and
wherein the detecting the face and the inner canthus, the determining the temperature measurement, the determining the body temperature, and the generating the notification are performed by a logic device, and wherein the artificial neural network and the detection system are implemented by the logic device.
