How to run m-files automatically ?

Hi,

I have collection of images to analyze using matlab. I made m-file code to analyze one image at a time, but it takes considerable time as there are hundreds of images to run.

Is there anyway to call the files in the folder and run one at a time automatically, without me designating the file name one by one?

Thank you very much for help.

D = dir('*.jpg');

for ii = 1:length(D)
   % Put your processing code here. Call image names as below...
   fprintf('Processing image named %s\n',D(ii).name);
end

Why are you using fprintf() inside imread()??? That's just used to write stuff to the command line or a file. Just use D(ii).name in the imread() directly.

fullFileName = fullfile(folder, D(ii).name);  % Folder is pwd unless you specify otherwise.
fprintf('About to read in %s...\n', fullFileName);
theImage = imread(fullFileName);
fprintf('Successfully read in %s\n', fullFileName);

Thank you for the quick reply. I found what was wrong.

I am confused. Who is using FPRINTF inside IMREAD?

Taehyung was but then after I said that, he went back and edited his code to delete it and say "Thank you very much"

And when you read this section of the FAQ, I suggest to read the rest also.

You could use the foll code

folder_cont = dir('C:\Users\*.jpg');
nsize = size((folder_cont),1);

for i = 1:nsize
str=strcat('C:\Users\',D(i).jpg);
im=imread(str);

%%do the processing of the image here

end
