Hello,
I'm currently working on tracking objects and I've been reading tutorials like this: [Optical flow](http://opencv-python-tutroals.readthedocs.io/en/latest/py_tutorials/py_video/py_lucas_kanade/py_lucas_kanade.html#lucas-kanade). And in the section related to Dense Optical Flow in OpenCV, they do this:
flow = cv2.calcOpticalFlowFarneback(prvs,next, None, 0.5, 3, 15, 3, 5, 1.2, 0)
As I understood, prvs and next are corresponding frames, None means that there are no tracking points defined, but I still can't get what these numbers mean. I've read [OpenCV documentation](http://docs.opencv.org/2.4/modules/video/doc/motion_analysis_and_object_tracking.html) about this several times, but it didn't help me too much.
Thank you in advance.
