Hi Wally,

This paper by Donoho is publicly available from Biometrika and has the
example I was talking about:

The algorithm I tried is the one he calls VisuShrink.  It's described more
rigorously in a paper in Information Theory (IEEE):

but you need a subscription to access the full text.  I find these papers
somewhat hard to follow (not my field) but the algorithm is pretty simple:
wavelet transform, reduce the magnitude of the coefficients by a magic
number related to the noise level, and inverse transform.
