How would I keep something in the field of view using correlation? (details inside)

What I want to do is read a video of a bunch of biological cells, then create a smaller field of view with one of the cells in the center. As each frame goes by, then "track" that cell to change the field of view frame by frame so that the cell stays in the field of view as long as possible.

What is the best way to do this? At least if anyone can help create a field of view, I'm fairly competent on using correlation to match frames and "track", I just need to be able to create that smaller field of view.

Thanks, first post so if I need to add anything let me know.

You're probably best off using imregister(). Look up posts by Alex Taylor - he wrote it the function: http://www.mathworks.com/matlabcentral/answers/?term=imregister I think he has a similar function for images that are moved by a substantial amount whereas imregister is for images that have not moved much between them.
