Extracting absolute temperature values from an Infrared video Not sure if this is the right place to be asking this, but it's my best bet.

So, I have a video captured from an infrared camera similar to the youtube video here. Can I get temperature information by analyzing the pixel data of any given frame? Also, if this needs prior calibration, how would I go about doing that?
There is no direct relation between the emitted intensity and temperature, as this depends on the body color and many other factors.

Anyway, you can get an approximation by calibration. For this  you use a reference object and heat it to known temperatures. You will draw a calibration curve (pixel intensities as a fuction of temperature) and possibly map a simple model (polynomial) onto it.
