MATLAB: Extracting frames from webcam !!

image processingvideo processing

Hi everyone, I want to extract the frame from my running webcam every 3 second I want to extract the frame and save it into variable to process it later so how I can do it please ?? I did this but not taking picture as running video ..
vid = videoinput('winvideo',2);
set(vid, 'FramesPerTrigger', Inf);
set(vid, 'ReturnedColorspace', 'rgb');
for i=1:10
    data = getsnapshot(vid);
    figure(i);
    imshow(data);
end

Best Answer

You are not saving the individual images.
One easy way is to use a cell array:
for i=1:10
    data{i} = snapshot(vid);
    figure(i);
    imshow(data{i});
end
I do not have the Image Acquisition Toolbox, only the Support Package for USB Webcams. This loop worked for me with it.
