I'm not familiar with the methods discussed in that paper, but I have
used the quadtree decomposition function from the MatLab Image
Processing Toolbox, qtdecomp().  It takes as arguments the 2-D matrix to
partition and a user-defined function implementing the splitting
decision and returns a sparse matrix representing the partition.
