matlab读取图像并转化为灰度图像

image = imread('C:\Users\Administrator\Desktop\图像降噪\src\original image\100.png');
image = rgb2gray(image);

image = imread('C:\Users\Administrator\Desktop\图像降噪\src\original image\1.bmp');image = rgb2gray(image);% figure ,imshow(image);% dlmwrite('filename.txt', image, ',', 0, 0) % image = image';figure ,imshow(image);fid = fopen('exp.txt','w');   fprintf(fid,'%d,',image);   fclose(fid); fid = fopen('exp.txt', 'r');

A =load('exp.txt');%读取exp.txt数据image2 = zeros(256,256,'uint8');for i = 1 : 256    for j = 1 : 256        image2(j,i) = A((i-1)*256+j);        endendfigure,imshow(image2);% B=dlmread('exp.txt',',')

% image = double(image);
