Abstract

It is well known that the noise processes corrupting an image are, in general, signal dependent. Under low signal-to-noise-ratio situations, the amount of signal information present in the signal-dependent noise may become a significant fraction of the total signal information. A simple technique designed to demonstrate the potential for signal extraction from signal-dependent noise is presented.
