Web4 aug. 2014 · The Wiener filter converts the seismic wavelet into any desired shape. For example, much like the inverse filter, a Wiener filter can be designed to convert the seismic wavelet into a spike. However, the Wiener filter differs from the inverse filter in that it is optimal in the least-squares sense. WebWIENER2 implements "Lee's sigma-filter" while deconvwnr performs Wiener deconvolution, so the functions have rather different purposes. 댓글을 달려면 … Web(4) 使用 Wiener 反卷积图像滤波器恢复与模糊核卷积后得到的图像，同时将噪声降至最低。 Wiener 滤波器旨在最大程度地减少低信噪比 (signal-to-noise ratio, SNR) 频率引起的噪声。Wiener 滤波器核是在频域中定义的，如下公式所示( SNR 越高，恢复的图像质量越高)： billy lester - from scratch 2022
