Hi Dimiter Prodanov,

You mean I shoudl put it into the filter directory of IJ.jar file?

Actually, I wanna inherit the BackgroundSubtracter class, but I don't know how to.
I mean, the whiteBackground in BackgroundSubtracter is a private one,
how can I access it in its subclass ? Or do you have any way?

Thanks.

Best wishes,
Bian Liu
