Matlab 实现图像的平移，旋转，缩放

%图像进行平移、旋转、缩放

clear;

close all;

img1=imread('C:\Users\Administrator\Desktop\DaiMa\ct.BMP');

%图像尺寸调整

img1=imresize(img1,[512,512]);%调整图片的尺寸

%img1=rgb2gray(img1);%真彩色图转换为灰度图

%figure,imshow(img1);

imwrite(img1,'ct.bmp');%保存图像

%I1=double(img1);

%img1=(I1-min(I1(:)))/(max(I1(:))-min(I1(:)))*255;

%平移 

se=translate(strel(1),[20 15]);%大小不变，进行Y,X方向平移

img2=imdilate(img1,se);

figure,imshow(img2);

imwrite(img2,'ct1.bmp');

%旋转

img3=imrotate(img2,10,'nearest','crop');

figure,imshow(img3);

imwrite(img3,'ct2.bmp');

%i=imread('C:\Users\Administrator\Desktop\DaiMa\ct.BMP');

%save('ct.txt','i','-ascii');

%缩放

%img4=imresize(img1,2);

%figure,imshow(img4);

%imwrite(img4,'ct4.jpg');
