【图像修复】基于GUI中值+均值+维纳+最小平方图像恢复【Matlab 772期】

一、简介

图像修复问题就是还原图像中缺失的部分。基于图像中已有信息，去还原图像中的缺失部分。

二、源代码

function varargout = hx1(varargin)
gui_Singleton = 1;
gui_State = struct('gui_Name',       mfilename, ...
                   'gui_Singleton',  gui_Singleton, ...
                   'gui_OpeningFcn', @hx1_OpeningFcn, ...
                   'gui_OutputFcn',  @hx1_OutputFcn, ...
                   'gui_LayoutFcn',  [] , ...
                   'gui_Callback',   []);
if nargin && ischar(varargin{1})
    gui_State.gui_Callback = str2func(varargin{1});
end

if nargout
    [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});
else
    gui_mainfcn(gui_State, varargin{:});
end

function hx1_OpeningFcn(hObject, eventdata, handles, varargin)
handles.output = hObject;
guidata(hObject, handles);

function varargout = hx1_OutputFcn(hObject, eventdata, handles) 
varargout{1} = handles.output;

function edit1_Callback(hObject, eventdata, handles)

if ispc && isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))
    set(hObject,'BackgroundColor','white');
end

function file_Callback(hObject, eventdata, handles)
