Hi Catherine

If you have a sequence of images taken from a static viewpoint you can subtract the first image from the rest of the images and this will give a rough idea of how different the subsequent images are.  This is easily achieved in ImageJ by opening an image sequence as a stack, duplicating the first image, then using the image calculator to subtract the duplicated first image from all the images in the stack.

Would be interesting to see your results!
