Image denoising based on MATLAB GUI Butterworth + median + Wiener + wavelet image denoising

function varargout = GUI_3(varargin)
% GUI_3 MATLAB code for GUI_3.fig
%      GUI_3, by itself, creates a new GUI_3 or raises the existing
%      singleton*.
%
%      H = GUI_3 returns the handle to a new GUI_3 or the handle to
%      the existing singleton*.
%
%      GUI_3('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in GUI_3.M with the given input arguments.
%
%      GUI_3('Property'.'Value',...). creates anew GUI_3 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before GUI_3_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to GUI_3_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one % instance to run (singleton)".
