How to combine Computer Vision Toolbox with Image Acquisition toolbox

Hi,

How can I combine these toolbox?

For example, if I would apply vision.OpticalFlow object to acquisition, how can I do it?

Not sure exactly what you're asking. My answer would be: use the Image Acquisition Toolbox to acquire data, and process that signal using Computer Vision Toolbox functions. However, I'm not sure if this answers your question.

Yes, it what I'm asking. Sorry for the strange form of my answer.

How can I acquire data using image acquisition toolbox and process what I'm acquiring by Computer Vision Toolbox in real-time ?

You're basically asking "How can I write and use programs in MATLAB" so I recommend you view some of Doug Hull's video tutorials: http://blogs.mathworks.com/videos/

I followed all the user guide of Image processing toolbox and Computer Vision Toolbox, and I saw that Computer Vision is used to process videofile. I would know if it can process a webcam video stream.

Yes you can. Just use

snappedImage = getsnapshot(videoObject);

to get a frame of live video from a video camera, instead of pulling it from a video file on disk.

Ok. But, for example, if with

vid = videoinput('nameadaptor', ID, 'Format');

I create the object for the acquisition by cam, and with

optical = vision.OpticalFlow;

I create the object for the optical flow...

how can I make to work optical flow object with acquisition object ?
