i want to save the videoFrame in the while loop as separate image in the Face Detection and Tracking Using the KLT Algorithm example so that each videoFrame is saved as a image for a demo i prepare...any one help me
note : i have seen some example using frame & frame rate in this case tracking is not only based on frame it is also based on visiblePoints so if there is less than 2 visiblePoints the loop will terminate.

If I understand your question correctly, all you need to do is have a call to imwrite inside the loop that writes the video frame with the markers for visible points and bounding box to a file.
So something like this:
Before the while loop:
nFrame = 1;
In the loop right at the end,
imwrite(videoFrame,['image_' double2str(nFrame)],'png');
n = n + 1;
