I can't be certain, but I believe they are there in the Java interface as they are pretty common functions.

The first would be to get the lunimance plane, same as the ellipse finder it looks to be the getLuminancePlane() method. You can do this based on color, but I'm not sure that is much more effective than the faster luminance approach. Second you'll want to thresholdHSL() or threshold ??? to get a BinaryImage type. The other particle filtering functions will be unique methods on a BinaryImage.

I'll help more if you could point to a doxygen or similar function reference for the Java WPILib. I wasn't able to locate one.
