Hello,
I am looking to use an intensity image acquired using a FLIR camera and their image capture software and essentially create a thermal image where I can identify the temperature at a specific temperature. I know that the camera is calibrated for temperature because it can take accurate spot temperature measurements, but I'm trying to make the acquired intensity image and convert it to a temperature scale. I'm pretty new to image processing so any help would be greatly appreciated! Also, the image is saved as .tiff format that has the original intensity values. For some reason using imshow(image) shows no data but adjusting the contrast with imadjust(image) produces a viewable image (but changes the pixel values...) just an observation.
Thanks!

Honestly, I have no idea in this context, are you looking for convert an intensity image to temperature distribution map, right? Please see the idea of ​​image acquisition in normal cameras and thermal imaging devices, you may get some clues.

an IR camera is measuring a flux, and mainly the emissivity. But emissivity depends on the materials in your image, so without a calibration for each material, you cannot know the temperature !
