Here is more information on IMAQ Vision, the extensive library of vision processing VIs for LabVIEW:
NI Product Page: Programmable Vision Functions. This page also mentions the Vision Development Module for LabVIEW, which includes IMAQ Vision and Vision Assistant. Vision Assistant is a powerful interactive environment that allows you to quickly prototype a vision application without programming. You can even generate LabVIEW code!
Please let me know if you have any further questions on these software packages.
