you need to capture snapshots from live video in order to process them.
vidobj = videoinput('winvideo');
snapshot = getsnapshot('vidobj');
imagesc(snapshot);
and if you want to acquire multiple frames do this:
for i = 1:5
snapshot = getsnapshot(vidobj);
imagesc(snapshot);
end
you need to have Image acquisition toolbox.go through demos.

why for lop is 1:5 what does 5 means here? thanks
See doc colon.
i meant why he is running loop 5 times .Is something related to 5
It's just meant as an example. You can run the loop as many times as you need to.
i am actually trying to capture a video being played on my laptop screen in minimized window. I do not wanna use videoreader('abcd.mp4'). I need to capture that part of screen where video is running. can u help me please here.
I don't know how to do that. It was a bad idea to accept an answer that does not do what you need. You might need to ask a new question, but make clear exactly what you want to do, giving details of the program that is playing the video.
