There is some pretty amazing work being done on Compressive Sensing at
the moment. Really it offers very lightweight compression of sensor
signals (allowing the data to be compressed by a cheap microcontroller
for example). Followed by more complex decompression on say a PC.
It's repercussions go way beyond that however into AI and data fusion.
There is an introductory article here:

I also have a very simple but effective Moving Average Filter based
Compressive Sensing algorithm here:

Not much to do with fractals you might complain. True but a random
projection is just a weak hashing algorithm.
A fractal is a hashing algorithm for real numbers. Perhaps later
random projections and fractals can be put together to do even greater
things with compressive sensing. And hello again to everyone here!
