1.添加椒盐噪声

function button_jiaoyan_Callback(hObject, eventdata, handles)%添加椒盐噪声
axes(handles.show_proImg);
global fpath;
img_2=imread(fpath);
img_2=rgb2gray(img_2);
img_2=imnoise(img_2,'salt & pepper',0.06);
imshow(img_2);
title('加入椒盐噪声后')

2.添加高斯噪声

 function pushbutton21_Callback(hObject, eventdata, handles)%加入高斯噪声
axes(handles.show_proImg);
global fpath;
img_2=imread(fpath);
img_2=rgb2gray(img_2);
img_2=imnoise(img_2,'gaussian');
imshow(img_2);
title('加入高斯噪声')

3.添加乘性噪声

function pushbutton22_Callback(hObject, eventdata, handles)%乘性噪声
axes(handles.show_proImg);
global fpath;
img_2=imread(fpath);
handles.img = imnoise(img_2,'speckle',0.04);
cla; imshow(handles.img);
guidata(hObject,handles);
title('乘性噪声');

4.添加泊松噪声

function butoon_bosong_Callback(hObject, eventdata, handles)%泊松噪声
axes(handles.show_proImg); 
global fpath;
img_2=imread(fpath);
img_2 = imnoise(img_2,'poisson');
cla;
imshow(img_2);
guidata(hObject,handles);
