Can anyone post a summary of the concept of wavelet transforms? I have
read that these are the "hot new thing."

In an attempt to solicit information, let me guess what they are. That
way, if you know but are too lazy to answer my first request, you
will be sorely tempted to  set me straight:-)

I would guess that they are a form of the general Fourier transform.
By this, I do not mean the traditional transform, but rather a class
of transforms characterized by the use of orthogonal functions - by this
definition a LaPlace (sp?) transform and a Walsh transform is also a 
Fourier transform. With wavelets, presumably someone found a nifty 
set of orthogonal, spanning functions that resemble solitons or
sinx/x functions or something else that is new and marvelous.

Well, am I close? Am I all wet? Please don't send arcane references, as
I am quite a distance from a good library.

Thanks (I hope).
