How can I make the centroid of bounding box to react to the line drawn inside a "LIVE" video?

Greetings,
As stated in the question title, I have a program that will help track object and have already draw a line so that it will show up a video only if the object was detected. However, no matter what I do, the centroid of the bounding object will not react to the line, any ideas on how to solve this? The figure below will show you a better idea on what I am trying to do. Here, I am trying to make a counter in such a way that, when an object(centroid of object) was crossing the green line, it will add 1 to the counter. I tried putting when the X-coordinate is less than 50, then the line will turn purple while it adds a counter. Of course, seeing that I posted it here means that it is a failure.

Thank you very much.

Well, not much we can do with what you have given us so all I can do is to give you encouragement that if you learn how to debug with this link that you'll eventually figure it out.

Your video adapter might have a frame rate property you can set. Run imaqtool and see what's there.

Something like
if yTop + height/2 > rows/2
% Above middle
rectangle('Position', [xLeft, yTop, width, height], 'EdgeColor', 'r');
else
% Below middle
rectangle('Position', [xLeft, yTop, width, height], 'EdgeColor', 'b');
end
