i have an .tir file which has temperature data (thermal image). Now i want to remove the background noise (background temperature data) without losing temperature data of the object.

this is an image taken from the thermal imaging camera. it is in .jpg format. but, i cannot extract temperature data from this.

What does "remove" mean? Replace it with white pixels? Crop the image to get a tight rectangle? Where does the temperature chart come from? Why do you want to import it instead of using a standard colorbar in Matlab?

As far as I understand the problem is, that you import the RGB-values in the JPEG image, but do not have the information about the relation between colors and temperatures. If this is the problem, you need to search this information in the function, which records the image and exports the data. You cannot magically create this inside Matlab, but this relation is a part of the measurement.
