MATLAB: Reading an image

reading image

I have a code

X=zeros(256,256,15)

 for x = 1:length(dirlist)
    i = imread([pathname, dirlist(x).name]);
    A=i;

X(:,:,x)=A;

save X

end

load X

i have saved 15 images in X,i have used load command,now please tell how to read those images

one way

for ii = 1:size(X,3)
    imshow(X(:,:,ii));
end

The same way you saved them:

for k = 1:10
  A = X(:,:,k);
  % do something with A
end

(Also, move the save command out of the loop -- it's just wasting time to save the data on every iteration.)

MATLAB: Subtracting velues in cell

The best thing would be to subtract first and do MAT2CELL second:

for xx = 1:length(dirlist(1))
x = imread([pathname, dirlist(xx).name]);  
x=rgb2gray(x);
C=imresize(x,[256 256]);
end
for xx = 1:length(dirlist)
x = imread([pathname, dirlist(xx).name]);  
x=rgb2gray(x);
C1=imresize(x,[256 256]);
end
D=mat2cell(C-C1,[128,128],[128,128]);

Alternatively, you can use CELLFUN:

D=cellfun(@(a,b) a-b, C1, C2, 'uni',0);
