how to implement real time imread

Greetings,

I need to read images and apply image processing algorithm
in real time. So I want to do 'imread' as soon as an image
is created in Matlab working directory.

I was thinking something like this:

1. Keep reading image files and store them using structure

2. If a new image is dropped into the folder and the new
list and the old list are different, do carry out image
processing algorithm

Is there a way I could make the Matlab to read images
forever? Should I just use while loop?

Is there a better way I could go about this problem?

Thanks, -Sean

Help exist - take a look at the file option.
