I had to find the required temperature values from my ROI in a thermal video. I extracted some frames and extracted the region of interested that is still in the form of pixels. Now I want to map temperature values to that ROI from my excel file that is basically extracted from the same frame. After that I have to test whether the values are exactly from the region of interest or not? Any idea about that or any example. Waiting for you kind response. Thanks

Like I said in your duplicate post:
Not exactly sure what " Now I want to map temperature values to that ROI from my excel file that is basically extracted from the same frame" means but if your ROI is a binary image mask, you can do
thermalImage(mask) = someValue;
To see if some value is in your ROI, you can do this:
pixelsInROI = thermalImage(mask);
if max(pixelsInROI == someValue) == 1
% someValue is the value of at least one of the pixels.
else
% someValue is NOT the value of at least one of the pixels.
end

Don't you have the original image? I don't want a screenshot with all that junk. Can't your camera save/export just the image only and not all that other unneeded stuff?
