Automatic 1-D de-noising
[XD,CXD,LXD] = wden(X,TPTR,SORH,SCAL,N,wname) [XD,CXD,LXD] = wden(C,L,TPTR,SORH,SCAL,N,wname)
: threshold rescaling
: 'one' for no rescaling
: 'sln' for rescaling using a single estimation of level noise based on first-level coefficients
: 'mln' for rescaling done using level-dependent estimation of level noise
: threshold selection rule
:'rigrsure' uses the principle of Stein's Unbiased Risk.
: 'heursure' is an heuristic variant of the first option.
: 'sqtwolog' for universal threshold
: 'minimaxi' for minimax thresholding
wden performs an automatic de-noising process of a one-dimensional signal using wavelets.
