图像去噪： Code for denoising images. This code differs from standard wavelet denoising techniques in that it uses non-orthogonal wavelets, and unlike existing techniques, ensures that phase information is preserved in the image. Phase information is of

Biorthogonal:Contents v802 -- Bi-Orthogonal Wavelet Transform tools ％ ％ The routines in this directory perform periodic- biorthogonal wavelet ％ analysis of 1-d and 2-d signals.

This routine performs a 1-D Periodic Orthogonal Wavelet decomposition. It also performs the row decomposition component of a 2-D wavelet transform. An input signal x[n] is low pass and high pass filtered and the resulting signals decimated by factor
