Have a look at the IMAQ Find Circular Edge VI. It gives you the best circle (based on its settings) as an output cluster, from which you can extract the radius.

Can you threshold the coins from the background? If so, I believe there is an example that uses Find Circular Objects to locate coins and measures their sizes to figure out what they are.

hello,i think you may help me for my problems.
I am new in labview software.
I am just now studying it. I have to develope project for detecting objects in live video.
Till this point i have done with capturing and displaying of live video. But i am not getting further steps.
I want to detect persons facial features from live video.
I have read some information regarding region of interest. Can i create such regions and then move them with the video?
Any help in this situation will be appreciated.
If you know anything then please let me know.
Thank you in advance.

You can declare region of interest and make a template of what you have to track in the move object . choose your score in matching the template carefully.
Try this first in VDS and then convert into labview it will make your job easier
