Thermal image how to measure the temperature of each pixel

I'm working on thermal camera image processing and I would like to show what every pixel means in temperature (Finite element analysis). How can I create such code?

Can the image process toolbox help me?

and also how can I put it in the code so it can give me temperatures for certain colors for the attached image?

You'd be best off using the FLIR camera that can export the temperature image directly, instead of the cheapest of their lineup (FLIR One) that only gives you pseudocolored images. It would be a lot easier and would be money well spent.

Otherwise, see my attached demo that allows you to specify the colorbar location and min and max temperature of the colorbar and builds a temperature image from the pseudocolored RGB image.

Of what flame? You didn't supply any image or data. And I actually already showed you how to get temperatures in my Answer above, so I really don't understand your question.

If you have any more questions, then start a new question, attach your data and code to read it in with the paperclip icon after you read this:

This is the image. By matlab code, how would i measure the temperature value?

[Image Analyst]

If that is all you have, you can't.

From this IR image. It is process from thermal imager

Again, this is not an Answer to @Mohamed Shembesh's question so you should have started a new question. Also, like I said, you can't because there is no color bar and even if there were how do we know what emissivity was used. Do you know the emissivity for a flame? Answer in your new post (don't reply here).
