Abstract: Various techniques are disclosed to provide for improved human body temperature detection using thermal images of an inner canthus. In one example, a method includes capturing a thermal image of a human being using a thermal imager. The method also includes detecting a face and an inner canthus of the human being in the thermal image using an artificial neural network. The method also includes determining a temperature measurement of the inner canthus using corresponding pixels of the thermal image. The method also includes determining a body temperature of the human being using the temperature measurement. Additional methods and systems are also provided.
