I am going to post the vi but just wondering is this the image you want to process or the real time image is different?

[kaus]

my motive is to object track the basic shapes like rectangle, circle and triangle in a single image.

Thanks for the help. Actually i need to identify a shape mounted on a moving vehicle. Based on it, i have to predict whether it is moving left,right, front or back and by how much measure.  I need to make a vi for that. Any idea.. ??

That is the reason why I asked you to post a real time image earlier. Since it going to be a moving object, will the size of the triangle also change?
