Image denoising with wavelet
We first load an image, and add some noise to it
The orthogonal wavelet transform is not very efficient for image denoising because it lacks translation invariance. This is why there is so many reconstruction artifact

ESPRIT的思想在于,将传感器阵列分解为两个完全相同的子阵列,两个子阵中每两个相对应的阵元具有相同的平移,即要求阵列具有平移不变性,每两个位移相同的阵元匹配成对。实际中许多阵列满足这个条件,比如等距直线阵。它还有一些改进演算法,如最小二乘ESPRIT (LS-ESPRIT),整体最小二乘ESPRIT(TLS-ESPRIT)等-Finding ideological positioning signal processing ESPRIT thought that t
