% --- Executes just before piture_procession is made visible.
function piture_procession_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% varargin   command line arguments to piture_procession (see VARARGIN)
% Choose default command line output for piture_procession
handles.output = hObject;

% Update handles structure
guidata(hObject, handles);
% UIWAIT makes piture_procession wait for user response (see UIRESUME)
% uiwait(handles.figure1);

% --- Outputs from this function are returned to the command line.
function varargout = piture_procession_OutputFcn(hObject, eventdata, handles)

%图像导入并显示
function pushbutton1_Callback(hObject, eventdata, handles)
global im %将im变量设置成全局变量，这样子其他控件的回调函数才能调用这里的im变量
[filename,filepath]=uigetfile({'*.bmp;*.jpg;*.png;*.jpeg;*.tif;*gif;*Image files'},'选择图像');%获取图像文件名和路径
if isequal(filename,0)||isequal(filepath,0)
    return;
end
image =[filepath,filename];%合成路径+文件名
im=imread(image);%imread()函数根据image中的路径和文件名找到图片，并将其读取到im中
axes(handles.axes1);%在显示图像之前，需要指定图像要显示在哪个坐标轴
imshow(im);%在坐标axes1显示图像

%添加高斯噪声
function pushbutton2_Callback(hObject, eventdata, handles)
global im %需要声明im是全局变量，这样子im就和其他控件的im是一样的值，否则就是个新的变量
i = imnoise(im,'gaussian');%imnoise()函数用来给图像添加噪声，可指定噪声的类型，这里是添加高斯噪声
axes(handles.axes2)
imshow(i);

%添加椒盐噪声
function pushbutton3_Callback(hObject, eventdata, handles)
global im
i = imnoise(im,'salt & pepper');
axes(handles.axes2)
imshow(i);

%添加泊松噪声
function pushbutton4_Callback(hObject, eventdata, handles)

imshow(i);

%用滑动条做图像增强
function slider6_Callback(hObject, eventdata, handles)

imshow(x1);

%滑动条设置
function slider6_CreateFcn(hObject, eventdata, handles)
if isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))
    set(hObject,'BackgroundColor',[.9 .9 .9]);
end

%灰度变化
function pushbutton5_Callback(hObject, eventdata, handles)
global im

imshow(y);

%去噪
function pushbutton6_Callback(hObject, eventdata, handles)
global im;
y=rgb2gray(im);
p = imnoise(y,'salt & pepper',0.1); %加10%的椒盐
axes(handles.axes1);
imshow(p);
g=medfilt2(p);
axes(handles.axes2);
imshow(g);

%旋转
function pushbutton7_Callback(hObject, eventdata, handles)
global im
theta=30;
p=imrotate(im,theta);
axes(handles.axes2);
imshow(p);

%二值化
function pushbutton8_Callback(hObject, eventdata, handles)
global im
y=rgb2gray(im);
n=graythresh(y);
axes(handles.axes2);
% im2bw(x,n);
output=imbinarize(y,n);
imshow(output);

% 保存
function pushbutton9_Callback(hObject, eventdata, handles)
% global b;
new_f_handle=figure('visible','off');
new_axes=copyobj(handles.axes2,new_f_handle); set(new_axes,'units','default','position','default');
