CNLTreg-package Complex-Valued Wavelet Lifting for Signal
Denoising
cnlt.reg Performs 'nondecimated' complex-valued wavelet
lifting for signal denoising
denoisepermC Denoises a signal using the complex-valued
lifting transform and multivariate soft
thresholding
denoisepermCh Denoises a signal using the complex-valued
lifting transform and multivariate soft
thresholding and heteroscedastic variance
computation
fwtnppermC Forward complex wavelet lifting transform
mthreshC Function to perform 'multiwavelet style'
level-dependent soft thresholding for
complex-valued wavelet coefficients
orthpredfilters Computes orthogonal filters
The main routines of the package are denoisepermC and cnlt.reg which perform complex-valued lifting-based denoising, using a single or a multiple (chosen) number of lifting trajectories, respectively.
