1. A temperature detection system for detecting a correlation between temperatures on a subject and a reference temperature, said system comprising:
one or more calibrated temperature reference devices;
an emissive source detector that captures one or more images;
a display; and
a processor in communication with a memory, said processor executing machine readable instructions for performing:
(a) receiving the one or more images from said emissive source detector, wherein at least one of the one or more images includes the subject and said one or more calibrated temperature reference devices;
(b) isolating said one or more calibrated temperature reference devices within the at least one of the one or more images and analyzing pixel values of said one or more calibrated temperature reference devices to find a mean reference temperature and a median reference temperature;
(c) comparing the mean reference temperature with the median reference temperature to determine when the median and mean reference temperatures are statistically similar, and using said mean and median reference temperatures to determine the reference temperature when the median and mean reference temperatures are statistically similar;
(d) mapping each pixel within the at least one of the one or more images to a specific thermal value based on said mean and median reference temperatures; and
(e) identifying any pixel in the least one of the one or more images with a temperature greater than said reference temperature and displaying said identified pixels on the display with a temperature greater than said reference temperature with a color and/or shape.
