Hi Wally,
This paper by Donoho is publicly available from Biometrika and has the
example I was talking about:
http://biomet.oxfordjournals.org/content/81/3/425.abstract
The algorithm I tried is the one he calls VisuShrink. It's described more
rigorously in a paper in Information Theory (IEEE):
http://ieeexplore.ieee.org/search/srchabstract.jsp?navigation=no&arnumber=382009
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.
Regards,
Brian
