... iterations

In the spirit of searching for an image decomposition with a minimum degree of freedom, it is desirable to develop heuristics to completely remove Aspen which were significant to begin with but have been rendered insignificant due to the addition of other Aspen in successive cycles. Furthermore, heuristics to merge different but similar Aspen will further help in reducing the degrees of freedom. Work on exploring these possibilities is in progress and will be reported in future papers.
