MATLAB: Use video Live stream

computer visionimageimage processingMATLABvideovideo processing

Hello guys. I need to have a live video stream on matlab. I prefer if it's not on GUIDE. I found one but it's a .dll file and I can't use it. When I call it's function i get error. Do they need to be complied into matlab in any way???

All I need is to be able to capture an image from video stream each half second or maybe more. I have a code to process images but I want them to be taken from live webcam.

I appreciate any help. Regards, Arman

You will need the Image Acquisition Toolbox for that. You can look at the examples provided at: https://www.mathworks.com/help/imaq/examples.html

A typical workflow will be:

vid = videoinput('winvideo'); img = getsnapshot(vid);

You can use a while loop here.

Folder = 'OUTPUT\';
vid = videoinput('winvideo', 1);
     
   % wait for 5 seconds
    
while true
  frames = getsnapshot(vid);
  pause(5);
  imwrite(frames, fullfile(Folder, sprintf('%06d.jpg', iframe)));
  iframe = iframe + 1;
end

Hope this does it.
