real time image processing ?

Hello, I have 3 CCTV cameras which working continuously, instead of saving video, they take snapshot each second and saving in different folders. I mean: camera one save an image for each second in folder A, camera two save image in folder B, camera 3 in folder C. I'd like to use Matlab for real time image processing, just wondering to know how can I read image from each folder contentiously? for offline processing already used this method for each image but its not working now:

srcFiles = dir('C:\New Folder\*.jpg');

for i = 1 : length(srcFiles)

    filename = strcat('C:\New Folder\',srcFiles(i).name);

    I = imread(filename);

    figure, imshow(I);
end

thank you Marry, your suggestion is just for offline processing i think. but in my case the number of images in each folder change in each second, for example at time 0 i have one image in each folder, then 3 seconds later i have 3 more (4 images) in each folder. what should i do for this kind of problem?

You can get the file date/time from dir(). Then sort them to figure out the newest one.
