基于matlab GUI小波、中值、维纳及频域上的滤波
二、源代码

function varargout = dsp1_2(varargin)
% DSP1_2 MATLAB code for dsp1_2.fig
%      DSP1_2, by itself, creates a new DSP1_2 or raises the existing
%      singleton*.
%
%      H = DSP1_2 returns the handle to a new DSP1_2 or the handle to
%      the existing singleton*.
%
%      DSP1_2('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in DSP1_2.M with the given input arguments.
%
%      DSP1_2('Property','Value',...) creates a new DSP1_2 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before dsp1_2_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to dsp1_2_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
