1. A vehicle system, comprising:
one or more far infrared (FIR) cameras;
and a processor, configured to:
classify a first object detected from one or more images of the one or more FIR cameras;
for a second object detected from the one or more images of the one or more FIR cameras having a relative temperature range coinciding with the first object and within an energy range of the first object, recognize the second object as having a classification of the first object,
wherein the energy range of the first object is based on a temperature and a distance to the first object; and
determine an energy range of the second object based on the classification of the first object.
