Extract Radiometric Data From Infrared Jpeg File?

I am desperate in solving the following puzzle: I use a thermal camera (a camera that captures thermal images by working in the infrared spectrum).The camera produces thermal jpeg files that includes visual (the picture one can see) together with the thermal data (thermal energy levels) in one jpeg fully radiometric(=file that holds energy data) file.

What I want to do is to try to extract the energy level data for each and every pixel of the image (usually 320X240) and store it in a table, using my old favorite vb.net if possible.
