Summary[edit]
DescriptionCMB Wiener filter example.png |
English: This figure demonstrates the effect of a Wiener filter on a noisy simulated observation of the Cosmic Microwave Background (CMB). The input data 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 and respectively.
The center panel shows the Wiener-filtered result, computed via . The right panel shows the true input signal. |
