Generalized Wiener filter
open-in-new
<p>The <a href="/facts/Wiener_filter/oGWdBTYa">Wiener filter</a> as originally proposed by <a href="/facts/Norbert_Wiener/cVMRAHCU">Norbert Wiener</a> is a <a href="/facts/Signal_processing/Npaja6zb">signal processing</a> <a href="/facts/Filter_(signal_processing)/vydJCNle">filter</a> which uses knowledge of the statistical properties of both the signal and the noise to reconstruct an optimal estimate of the signal from a noisy one-dimensional time-ordered data stream. The generalized Wiener filter generalizes the same idea beyond the domain of one-dimensional time-ordered signal processing, with two-dimensional <a href="/facts/Image_processing/zenalNCf">image processing</a> being the most common application. </p>
