Could you post a sample image of what the result would look like?

It is not possible to do that given only that information.

My speculation is that you did not ask the right question. I suspect that your question is an attempted repost of http://uk.mathworks.com/matlabcentral/answers/259278-how-i-get-this, which in turn is a rephrasing of http://uk.mathworks.com/matlabcentral/answers/259083-extract-the-difference-betwwen-2-images in which you were told what you would have to do but you do not appear willing to do so.

I guess I need to phrase this more strongly:

You must do stereo rectification in order to figure out where the objects are in the scene and how big they are in each dimension. Just having two difference images from different views is not enough. Stereo rectification involves doing camera calibration one way or another, whether that is by placing checkerboard patterns in the scene or by placing an item of known size at a known position. You can only do 3 dimensional reconstruction after you figure out what perspective view each of the two cameras has.
