| Keywords: CMB Wiener filter example.png This figure demonstrates the effect of a Wiener filter on a noisy simulated observation of the Cosmic Microwave Background CMB The input data <math>d</math> is shown on the left and is the sum of CMB which is a Gaussian random field which is strongly correlated in real space but diagonal in frequency space and a noise field which has independent values in each pixel but increasing standard deviation towards the edge The signal and noise have covariance <math>S</math> and <math>N</math> respectively The center panel shows the Wiener-filtered result computed via <math>\hat s S -1 +N -1 -1 N -1 d</math> The right panel shows the true input signal en wikipedia 2014-10-03 Amaurea wikipedia en Cc-zero user at project Amaurea wikipedia en Original upload log en wikipedia CMB_Wiener_filter_example png wikitable - 2014-10-03 17 45 1560×557× 1993585 bytes Amaurea <nowiki>This figure demonstrates the effect of a Wiener filter on a noisy simulated observation of the Cosmic Microwave Background CMB The input data <math>d</d> is shown on the left and is the sum of </nowiki> Uncategorized 2015 October 18 | ||||
