Hi!
I have a project. What happens is that I put a thermal image in image processor and then I want MATLAB to determine where in the image is the heat (the red-yellow) part of the image.
can you please help me?

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.
"I converted the thermal image to greyscaled image" <= well there's your problem. DON'T DO THAT. Keep the thermal image as it is, with units of temperature as given by your instrument. DO NOT convert units to gray levels. Keep your thermal image unconverted and you'll have the proper units or Kelvin or Celcius or whatever.
