GUI.zip_GUI静态文本_按钮文本框_轴控件的使用_静态文本、编辑框、按钮的使用

一、实验任务1：静态文本、编辑框、按钮的使用 function pushbutton1_Callback(hObject, eventdata, handles) a = get(handles.edit1,'String'); b = get(handles.edit2,'String'); total = str2num(a) + str2num(b); c = num2str(total); set(handles.text4,'String',c); guidata(hObject, handles); 实验任务2：轴控件的使用 function pushbutton1_Callback(hObject, eventdata, handles) fd = get(handles.edit1,'String') axes(handles.axes1); f1 = ezplot(fd); col = get(handles.edit2,'String') set(f1,'Color',col); wid = get(handles.edit3,'String') set(f1,'LineWidth',str2num(wid)); grid on; 分别输入：sin(x),cos(x),sin(x)/x,exp(2*x),u^2-v^2，以及颜色和线宽，绘制图形 function pushbutton1_Callback(hObject, eventdata, handles) (1)读入与显示图像 imdata=imread('lena.bmp'); imshow(imdata) imdata1=imread('lena.jpg'); figure imshow(imdata1) (2)读入与显示指定灰度范围内图像 figure(2) imshow(imdata,[64,128]) (3)显示颜色条 figure(3) imshow(imdata1) colorbar (4)显示子图像 figure(4) subplot(121); subimage(imdata); subplot(122); subimage(imdata1); 2．图像的几何运算 (1)旋转图像 function pushbutton2_Callback(hObject, eventdata, handles) global imdata; J1=imrotate(imdata,-45,'bicubic'); J2=imrotate(imdata,45,'bilinear','crop'); J3=imrotate(imdata,45,'bilinear','loose'); subimage(J1); (2)缩放图像 function pushbutton3_Callback(hObject, eventdata, handles) global imdata; J1=imresize(imdata,0.2); J2=imresize(J1,15,'bicubic'); J3=imresize(J1,15,'bilinear'); figure subplot(221);subimage(imdata); subplot(222); subimage(J1); subplot(223);subimage(J2); subplot(224);subimage(J3); (3)裁剪图像 function pushbutton4_Callback(hObject, eventdata, handles) global imdata; I2=imcrop(imdata,[75 68 130 112]); figure subplot(121);subimage(imdata); subplot(122); subimage(I2); 3．图像直方图 (1)显示直方图 function pushbutton5_Callback(hObject, eventdata, handles) global imdata; figure subplot(121);subimage(imdata); subplot(122); imhist(imdata); (2)直方图均衡化 function pushbutton6_Callback(hObject, eventdata, handles) global imdata; J=histeq(imdata); figure subplot(221);subimage(imdata); subplot(222); imhist(imdata) subplot(223);subimage(J); subplot(224);imhist(J); 4．图像滤波 中值滤波 function pushbutton7_Callback(hObject, eventdata, handles) global imdata; G1=imnoise(imdata,'salt & pepper',0.01); K1=medfilt2(G1); G2=imnoise(imdata,'gaussian',0.01); K2=medfilt2(G1); figure subplot(231);subimage(imdata); subplot(232); subimage(G1); subplot(233);subimage(K1); subplot(234);subimage(imdata); subplot(235);subimage(G2); subplot(236);subimage(K2); 均值滤波 function pushbutton8_Callback(hObject, eventdata, handles) global imdata; G1=imnoise(imdata,'salt & pepper',0.01); K1=filter2(fspecial('average',3),G1)/255; G2=imnoise(imdata,'gaussian',0.01); K2=filter2(fspecial('average',3),G2)/255; figure subplot(231);subimage(imdata); subplot(232); subimage(G1); subplot(233);subimage(K1); subplot(234);subimage(imdata); subplot(235);subimage(G2); subplot(236);subimage(K2); 5．图像分割 function pushbutton9_Callback(hObject, eventdata, handles) global imdata; level=graythresh(imdata); BW=im2bw(imdata,level); figure subplot(121);subimage(imdata); subplot(122); subimage(BW); 6．图像灰度均值、中值、标准差、方差 均值 >> imdata=imread('lena.bmp'); >> mean(mean(imdata)) ans = 123.5448 中值 >> imdata=imread('lena.bmp'); >> imdata=double(imdata); >> median(median(imdata)) ans = 140 标准差 >> imdata=imread('lena.bmp'); imdata=double(imdata); std(std(imdata)) ans = 12.6371 方差 imdata=imread('lena.bmp'); imdata=double(imdata); var(var(imdata)) ans = 8.3523e+05 7.在GUI中完成图像处理功能 加载图像按钮: function pushbutton1_Callback(hObject, eventdata, handles) 旋转图像按钮： function pushbutton2_Callback(hObject, eventdata, handles) 缩放图像按钮: function pushbutton3_Callback(hObject, eventdata, handles)
