This procedure is
useful for comparing and visualizing the differences between the 3 wavelet
shrinkage techniques in the cases of lower dimensional (1D and 2D) images.
You need to have executed "MultiDim_WT" first
before you call "MultiDim_IWT_varThresh"!
The only interactive routine in WAIR 2.0 is "MultiDim_IWT_varThresh".
This WAIR command is used to obtain the multi-dimensional
inverse wavelet transform (IWT)
of a signal using one of 3 possible wavelet thresholding schemes,
Uniform (at various levels), Donoho-Johnstone (DJ) and Dinov-Sumners (DS)
frequency adaptive approach (see the technical notes).
This routines requires no arguments or input parameters. After calling
"MultiDim_IWT_varThresh" follow the interactive instructions - you will be
asked to input certain information.
- This interactive routine
will determine the IWT of a signal after applying a
wavelet shrinkage to the wavelet coefficients.
