I have a program to process all the JPEG photos in a folder. But what I want to do is to run the program once every time a new image is stored in the folder. Any ideas to do so?
My current code is something like that:
srcFiles = dir('C:\FTP\testing2\*.jpg');
for i = 1 : length(srcFiles)
filename = strcat('C:\FTP\testing2\', srcFiles(i).name);
I = imread(filename);
...........rest of my code..........
end

How are you defining what's "new"? New since last time you ran the program? If so, then are you saving, somewhere, the date and time of the last time you checked the folder or ran your script?

folder='C:\FTP\testing2'
type='*.jpg'
srcFiles = dir(fullfile(folder,type));
for ii= 1 : length(srcFiles)
filename = fullfile(folder, srcFiles(ii).name);
I = imread(filename);
%Your code
%Store the result in a cell array, for example
Y{k}=I
end
What is the problem with your code

That depends on how many files are contained in your folder. Check the number of files by typing
folder='C:\FTP\testing2'
type='*.jpg'
srcFiles = dir(fullfile(folder,type))
size(srcFiles )

folder='C:\FTP\testing2'
type='*.jpg'
for k=:100
srcFiles = dir(fullfile(folder,type));
if ~isempty(srcFiles)
dat=datenum({srcFiles.date})
[~,ii]=min(dat)
nam=srcFiles(ii).name
filename = fullfile(folder, nam);
I = imread(filename);
%Your code
wait(2)
movefile(filename,fullfile(new_folder,nam)
end
