I need to detect smoke in a 3 frame image sequence with time difference.
I segmented some suspicious regions in the image. I need a method to detect if there are changes in the region by using frames. I calculated the NCC value of the region between two frames, but need other methods to decide about smoke.

how about an image subtraction or absolute difference?
