The MATLAB Graph object does all kinds of great graph algorithm related things, including shortest paths, max flow, and minimum spanning trees.

As of right now, there are no utility functions that ship with MATLAB for moving a 2-D image grid to a graph object representation, but there is a MATLAB File Exchange contribution that does exactly this:

Together, it is very easy to do what you want:
A = imread('pout.tif');
G = imageGraph(size(A));
tree = minspantree(G);

Hi Alex,
How do you visualize the results of "G" and "tree"?
Thanks,
