I have no experience with it, but the Labview code lets you play with threshold values as you operate the camera. You should check the Labview subforum for this; there are some people from NI who know much much more about it than me.
I'm sorry, but the "detect rectangles" code is only in C++ and labview... I'm relatively sure that if sample code is posted like it is most years, it will contain rectangle detection code (that is,
if sample code is posted). Once you find a nice threshold, you should look at the particle reports, since those are what you will be analyzing. You can get the bounding rectangle of a piece of the image, and know the expected area filled (since you know the width of the tape), and can compare that to the particle filled area...but i would concentrate on the thresholding for now
Everyone is a noob sometime, that's what these forums (and FIRST) are for
