v = VideoReader('exampleVideo.mp4'); 
time = [10, 20, 30, 40, 50]; %How to automatically read the image corresponding to each second.
for i=1:numel(time) 
    if time(i)<v.Duration 
        v.CurrentTime = time(i); 
        frame = readFrame(v); 
        figure; imshow(frame); %Perform processing on the frame here 
    end 
end
