Compressive Sensing

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:
