How can you detect irregular edges using the IMAQ add on?

[Dander]

Im currently trying to use the IMAQ add-on for LabView to detect the edges of an irregular image. I have attached the image I am trying to detect the edges of. I have tried using everything in the "locate edges" sub-pannel (i.e.. imaq find edge, imaq find circular edge etc.) but none of them have yielded any favorable results. I think the "IMAQ edge tool 3 IV" might be what im trying to find however I don't understand how to get any usable data out of it.

Thank you, all comments and help are greatly appreciated.

Hi Dander, 

I am not sure exactly what types of edges you are trying to acquire, but I used one of the examples from our Example Finder and was able to detect edges on your image.  I will say that with the image that you are using, the edges are not very well defined, so you may not get a 100% accurate measurement.  The example that I was using uses the IMAQ Edge Tool 3 VI and the example can be found by going in LabVIEW to Help>>Find Examples...  From there, you will go to Toolkits and Modules>>Vision>>Functions>>Edge Detection Example.vi.  After that, you will remove the build path function and input a path to the image.  I hope this helps!
