Hi,

How can I combine these toolbox?

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

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 ?
