Use Yair's techniques to create an invisible frame. Overlay it over the area of interest. getframe() to get what is "underneath".

This technique should in theory not work over any area that contains DRM (Digital Rights Management) controlled output, such as DVD videos.

Any reference where to find this technique? Just to have the answer complete :)

Actually I was looking for it because I want my software to respond to what appears there.

Example: You open a shooter game and make a code to detect the enemies and aim at them automatically. Instead of using a webcam pointing to my monitor hah.

I want MATLAB to do everything too but I don't think MATLAB provides screen recording capability yet. Doug Hull did a lot of video tutorials. He must have used some third-party tool. There are lots of third-party tools out there. Watch Doug's video to see if you like it. Shoot him an email asking which tool did he use.

In addition to Walter's answer above, you could also use my ScreenCapture utility to capture any screen rectangle (x,y,width,height): http://www.mathworks.com/matlabcentral/fileexchange/24323-screencapture-get-a-screen-capture-of-a-figure-frame-or-component
