.Wavelet.Denoising.denoisGUI

Information

This function is a modified version of the function denois. It provides graphic user interface (GUI) for parameter input and displaying denoising results. Instead of filter banks, the wavelet is specified with its name. The original data, the decomposed data in different levels, the denoised data in all levels and the denoised data are displayed with diagrams. In addition, the noise that is removed from the signal is displayed in a diagram, too.

The default input values provide an example to show the functionality of this function.
