WebApr 17, 2024 · Wiener filter is an age-old benchmark for image denoising and restoration [ 23 ]. This filter needs a degradation function for denoising or restoration. The better the degradation function is, the more denoising is achievable by Wiener filter. BM3D uses the basic estimated image from the first step as the degradation function of Wiener filter. http://www.inass.org/2024/2024022903.pdf proposed texas abortion law
