1. A method including the steps of: obtaining a base signal including a plurality of signal components; performing a higher level pyramidal decomposition of the base signal to generate a higher level decomposed signal; performing a lower level pyramidal decomposition of the first decomposed signal to generate a lower level decomposed signal; increasing, using the higher level decomposed signal to other signal components of a higher level decomposed signal to generate a first modified signal; and increasing, using the first modified signal, a ratio of a desired signal component of the base signal to other signal components of the base signal to generate an improved base signal.
