Yes, that should work. You will have to take mode of the displacement to get the most accurate estimation of the rigid displacement between the two images.
If you have 2D images, you can use https://github.com/FranckLab/qDIC.
Then I suppose that I can use the volumeMapping.m to apply the displacement found previously to the volume ?
The volumeMapping function is probably a bit too specialized since it does both the forward and backward mapping. A simpler solution is to either re-interpolate onto a shifted grid or use the Matlab built-in affine3d (and related) function.
For an example of re-interpolation look at volumeMapping, but only implement the "forward" part with a single uniform value of displacement measured from running FIDVC. Although, you can use Matlab built-in interpolation instead of the mex interpolation, since you'll only need to do it once.

Hello, I'd like to align 2 stacks of images so I'm wondering whether I can use FIDVC to find the displacement between the two stacks then apply this displacement to one of the images for the registration? Thank you,
