Compressed sensing (also known as compressive sensing, compressive sampling, or sparse sampling) is a signal processing technique for efficiently acquiring and reconstructing a signal, by finding solutions to underdetermined linear systems. This takes advantage of the signal's sparseness or compressibility in some domain, allowing the entire signal to be determined from relatively few measurements.Tomography, such as MRI and X-ray CT, is a prominent application.

Famous quotes containing the words compressed and/or sensing:
“Give up the belief that mind is, even temporarily, compressed within the skull, and you will quickly become more manly or womanly. You will understand yourself and your Maker better than before.”
—Mary Baker Eddy (1821–1910)
“Something was still there, that something that distinguishes an artist from a performer: the revealing of self. Here I be. Not for long, but here I be. In sensing her mortality, we sensed our own.”
—Studs Terkel (b. 1912)
