Hi Everyone
I have code which plays a video like that
vidobj=VideoReader('.avi');
frames=vidobj.Numberofframes; for f=1:frames thisframe=read(vidobj,f); figure(1);imshow(thisframe); Progress=fprintf('video is played'); end
Here I want to control this loop by displaying Progress message just one time not everytime when frames grow.Because as soon as number of frames increase the message is iteratively occuring in matlab command window.How can I control this statement?,
Thanks

Check the for loop counter when displaying the progress. You want to display progress only when counter is 1.
Use this if-else-end

Good.Actaully I am detecting blob from input video by subtracting background and getting binary image.So what I am trying to do is when the blob appear it shows message in command window as I did it like that using connected component labelling
measurements = regionprops(labeledImage,'BoundingBox','Centroid');
if isempty(measurements)
fprintf('there is nothing at frame',f);
else
fprintf('it detected at frame',f);
end
But hese two messages are appearing every iteration i want to restrit them just one time for example if something detected then it shows message when something is not then it show there is nothing.
Thanks
