No problem! I am glad this worked for you. Please check out the documentation for the Computer Vision System Toolbox. There may be other functionality there that you can use.
If you are trying to do 3D reconstruction of a face from motion, vision.PointTracker would be useful. If you are doing stereo, there are good examples of how to do feature matching and stereo rectification that come with the toolbox.
