Hey there,
I have 2 image one is RGB image the other one is its thermal version. I wanted to combine those 2 images. Thermal areas should be stay original RGB colors. In literature is there any special keyword to this operation. I search it on the IEEXPLORE and i didn't find it. I wanted to see some algoritms to implement it.
Thanks

There are an infinite number of ways you could "combine" them. For example you could add them, subtract them, divide them, etc. There is not just one way to combine them so until you explain what "combine" means to you, no one can answer.
The only way to "combine them" and have the thermal image "stay original" pseudocolored image colors is to not have the visible light image show up at all in the combination.

Thanks for the answer, i think merge is the right word to explain this operation. I found some articles and algorithms based on "Curvelet Transform" and it is good start for me.

combinedImage = RGBImage;
mask = repmat(ThermalImage >= some_threshold, 1, 1, 3);
combinedImage(mask) = repmat(ThermalImage(mask), 1, 1, 3);
