cha2_3_1.m

这是我在学习matlab时写的一些简单的图形处理的例子,初学者可以看一下!

I=imread('standard_lena.bmp');
I2=imresize(I,0.125);
Z1=interp2(double(I2),2,'nearest');
Z1=uint8(Z1);
figure(1);
imshow(I);
figure(2);
imshow(Z1);
imwrite(Z1,'cha2_3_1_1.bmp','bmp');
Z2=interp2(double(I2),2,'linear');
Z2=uint8(Z2);
figure(3);
imshow(Z2);
imwrite(Z2,'cha2_3_1_2.bmp','bmp');
Z3=interp2(double(I2),2,'spline');
Z3=uint8(Z3);
figure(4);
imshow(Z3);
imwrite(Z3,'cha2_3_1_3.bmp','bmp');
Z4=interp2(double(I2),2,'cubic');
Z4=uint8(Z4);
figure(5);
imshow(Z4);
imwrite(Z4,'cha2_3_1_4.bmp','bmp');
