How can I do the same task with a loop in the step function?

Hello,

Please can anyone help me how can i correct this? I want to repeat taking pictures of the face detected, every 3 seconds, and save it in a file. (NB: the for..end is just for the video reader). Thank you.

for taoefaeffadef = 1:100
    videoFrame = step(videoFileReader);
    matchPic = imcropPolygon(bboxPolygon,videoFrame);
    matchPic = cutPic(matchPic);
    imwrite(matchPic,'test2.jpg');
    ....
end

I'm not sure what you're asking. If you want to take snapshots every 3 seconds and save to files on disk, then put this in the loop:

thisImage = getsnapshot();
filename = sprintf('Image %d.png', taoefaeffadef);  % Change filename at each iteration.
imwrite(thisImage, filename); % Save to disk.
pause(3); % Wait 3 seconds
