How do you take a live video feed from a webcam and selectively extract frames of it? Do I need a special toolbox or can this be done through normal matlab functions?

I have the image acquisition toolbox, but haven't seen a good way to use it for this yet...

  1. make sure that the webcam is properly installed and connected.

  2. type the following code: 

    obj = videoinput('winvideo', 1);
preview(obj)

this shall generate a window capturing live video input.

The image acquisition toolbox is all you need. Just look at the documentation and it should be pretty straight forward.
