Hi,

I have been running my openCV setup on windows until now, but now I need to change to Ubuntu. Because of this, I was unable to create a .jar file for openCV version 3.x so I ended up with version 2.4.13.

This means that some of the lines of code that I had (perfectly working in Windows with openCV 3.1) no longer work.

I had the following line:

BackgroundSubtractorMOG2 mog2 = Video.createBackgroundSubtractorMOG2();

Now, I am trying to change this to work with openCV version 2.4.13, but I'm simply not able to.

I have tried the following line

mog2 = org.opencv.video.BackgroundSubtractorMOG();

but this gives me the following: org.opencv.video cannot be resolved to a type.

What can I do to make this run on my current setup?

try: mog = new org.opencv.video.BackgroundSubtractorMOG();

It worked. So all it needed was the "new" added before. Btw, it also seems to work with BackgroundSubtractorMOG2, not just the ordinary MOG.

you need a newin java for any object, that is not a simple number.

(opencv3 avoided that by having a "factory pattern" instead of a constructor)

Yeah, I know that. I simply overlooked the fact due to I looked to much on the old code. Anyway, thanks again.
