Pattern Recognition in a Photo

[Guillermo_Rigal]

Hello everyone,

I'm trying to use Labview in order to do a recognition of circles (and afterwards count the number of them) from already saved photographs (is to say, not "in time recognition"), but I don't know how to do it. Is there any way to do it?? By the way, I'm using Labview 8.0.

Thanks a lot!!

Hi G

Have you taken a look at the 'Particle Analysis Example.vi' - you can find it under Examples > Toolkits and Modules > Vision > Functions

You'd need the vision toolkit to do this though, I don't know of another way you could do this using only native LabVIEW code.

Kind Regards

Hi,

I have an example on the NI Community related to detecting circular features. It is LV2009, though.
