I'm in the same boat. After some searching I found
this class, which is relevant for Java users. (Thanks to Team 1203 for hosting the Javadoc online.) I haven't had much time to look through it yet, but it looks like a bunch of useful analysis can be done with the
MeasureParticle method; check out all the options in the
MeasurementType class. I don't know if the whole NIVision library is wrapped, but there's far more material than there was last year.
This class should probably be mentioned more prominently somewhere in the documentation... or maybe I'm just bad at looking for things
.
EDIT: This is more of a response to the previous post than to the OP. Basically, it looks like a bunch of useful vision processing functions are easily accessible with Java; it's only if you want to provide your own C code that you need to mess around with JNA.
