compressed sensing Last modified: Tuesday, December 11, 2007
An alternative theory to Nyquist's Law that indicates signals and images can be reconstructed from fewer measurements than what is usually considered necessary. In contrast, Nyquist's Law states that a signal must be sampled at least twice its highest analog frequency in order to extract all of the information. Also called compressive sampling.

Compressive Sensing Resources  Over the past few years, a new theory of "compressive sensing" has begun to emerge, in which the signal is sampled (and simultaneously compressed) at a greatly reduced rate.
