如matrix1zeros(4,5);%4*5的矩阵#xff0c;矩阵中每个元素都为0
matrix2zeros(4,5,3);%4*5*3的数组#xff0c;数组中每个元素都为0 下面举一个将图像存到数组的例子
对RGB图片1.jpg#xff0c;2.jpg#xff1b;大小为700*500…zeros为创建一个值为零的数组
如matrix1zeros(4,5);%4*5的矩阵矩阵中每个元素都为0
matrix2zeros(4,5,3);%4*5*3的数组数组中每个元素都为0 下面举一个将图像存到数组的例子
对RGB图片1.jpg2.jpg大小为700*500*3 创建4D空数组700*500*3*2
imgzeros(700,500,3,2);
直接将图片赋予数组会发现不是原图代码及运行结果如下
img1imread(strcat(C:\Users\Administrator\Desktop\,1.jpg)); img2imread(strcat(C:\Users\Administrator\Desktop\,2.jpg)); % img1_1im2double(img1); % img2_2im2double(img2); imgzeros(700,500,3,4); img(:,:,:,1)img1; img(:,:,:,2)img2; % img(:,:,:,3)img1_1; % img(:,:,:,4)img2_2; figure(1) subplot(4,2,1),imshow(img1); subplot(4,2,2),imshow(img2); % subplot(4,2,3),imshow(img1_1); % subplot(4,2,4),imshow(img2_2); subplot(4,2,5),imshow(img(:,:,:,1)); subplot(4,2,6),imshow(img(:,:,:,2)); % subplot(4,2,7),imshow(img(:,:,:,3)); % subplot(4,2,8),imshow(img(:,:,:,4));
运行结果 如果将图片转为双精度型则可正常代码结果如下 img1imread(strcat(C:\Users\Administrator\Desktop\,1.jpg)); img2imread(strcat(C:\Users\Administrator\Desktop\,2.jpg)); img1_1im2double(img1); img2_2im2double(img2); imgzeros(700,500,3,4); img(:,:,:,1)img1; img(:,:,:,2)img2; img(:,:,:,3)img1_1; img(:,:,:,4)img2_2; figure(1) subplot(4,2,1),imshow(img1); subplot(4,2,2),imshow(img2); subplot(4,2,3),imshow(img1_1); subplot(4,2,4),imshow(img2_2); subplot(4,2,5),imshow(img(:,:,:,1)); subplot(4,2,6),imshow(img(:,:,:,2)); subplot(4,2,7),imshow(img(:,:,:,3)); subplot(4,2,8),imshow(img(:,:,:,4)); 结果
