A good point for legacy material...
Those algorithms are provided by a french startup called Let it wave :

It has apparently obtained very favourable comments from Yves Faroudja himself,
according to this article :

Hardware implementation on Altera FPGAs are available :

Bandelets are a derivative of wavelets. Interestingly , one of the creators of
the company,
Stephane Mallat, is a man whose name will appear in any book retracing the
history of
wavelet theory, so he must know what he is talking about.
They also do image restoration for seismic, satellite or medical stuff, and
image compression (down to 500 bytes for an Id photo with very acceptable
quality, see the demo on their home page.
No way to try it on your PC, though, as they want to keep control on their
product and will not spread it over the internet.
