I have let suppose have 20 images in which 10 are standard image and 10 are reference images. I consider standard image are those images that don't have tumour (pixels of intensity 255)and reference that contains tumours so I read the directory as
sdirectory =('');
images = dir('*.jpg'); % as i have images of jpg format.
n_files = length(images);
for i = 1 : n_files;
current_file = images(i).name;
I{i} = imread(current_file ;
end
but I want to separate images if image has pixels of 255 intensity then name them reference image else consider them standard image .
I need help.

it would be helpful if you could upload a picture of a standard image and that of a reference image.

here in the image that have white balls is considered as reference image because the image have disk shapes that have 255 intensities and the other one is standard image

I fixed your code's formatting but as thanks I'd like you to read this: http://www.mathworks.com/matlabcentral/answers/13205-tutorial-how-to-format-your-question-with-markup. By the way, do you want to know some of the things wrong with your code?

% test image
Img = zeros(20, 20);
Img(5:15,5:15)=1;
% Find if '255' intensity pixels exist in the image
temp = find(Img==255);
if isempty(temp)
display('No tumour');
else
display('Tumour');
end
