Description

 

This VI uses NI-VISION functions developed in Vision Assistant to determine the level of concavity of a binary image in LabVIEW. This VI helps the user analyze (measure length and area) of the convex hull region of a morphological blob. For more information on morphology, check out the Image Analysis and Processing Developer Zone article. The NI-Vision Concepts Manual is also a great resource. Page 9-31 of the manual describes the function of the Convex Hull VI.

 

The SCR file from Vision Assistant is also attached. Enjoy!

Good stuff.  I'm not a vision guy so maybe it's enough, but could you add a little more description of how this is used?  .
