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);
end
end
figure,imshow(image2);
% B=dlmread('exp.txt',',')
% image = double(image);
