I have an RGB color image and a corresponding thermal image, generated by the same thermal camera. I'd like to check if these two images are aligned. so my question is how can I know if these two images of the same size are aligned or co-registred? are there any metrics or measurements that allow that?
Thank you in advance

I usually use this simple scheme
I1 = im2bw(RGB);
I2 = im2bw(THERMAL);
imshow(cat(3,I1*255,I2*255,I1*0))

Use rgb2gray instead (mistake)
I1 = rgb2gray(RGB);
I2 = rgb2gray(THERMAL);
imshow(cat(3,I1,I2,I1*0))

Thank you darova for your answer, but what I would like to get is a quantitative result, i.e. the measured gap between the two images. Maybe I didn't express myself well.
