Hello,

Try to use imshow(I,[])

or montage(I, 'DisplayRange', []);

i am applying median filter to the dicom images but errorsss... :(

here is the code

dicomlist = dir(fullfile(pwd,'Images','*.dcm'));

for cnt = 1 : numel(dicomlist)

I{cnt} = dicomread(fullfile(pwd,'Images',dicomlist(cnt).name));

end

for num = 1: numel(dicomlist)

K{num}=medfilt2(I{num});

end

ERRORS:-

??? Error using ==> ordf

Out of range value in OFFSETS.

Error in ==> ordfilt2 at 82

B = ordf(A, order, offsets, [padSize padSize] + 1, ...

Error in ==> medfilt2 at 65

b = ordfilt2(a, order, domain, padopt);

Hi,

It works on my machine. And no error found

dicomlist = dir(fullfile(pwd,'Images','*.dcm'));

for cnt = 1 : numel(dicomlist)

I{cnt} = dicomread(fullfile(pwd,'Images',dicomlist(cnt).name));

end

for num = 1: numel(dicomlist)

K{num} = medfilt2(I{num});

figure, imshow(K{num},[]);

end

i think its the problem of memory...

if i am applying this on 700 images than it works...
