Default parameters of DualTVL1

I would like to know which are the default values of the Dual TV-L1 algorithm, defined with createOptFlow_DualTVL1(). I need to find a good way for computing the method in realtime, and to know these values would be so useful. I cannot find them anywhere...

Thank you so much!!

You can found all default parameters here: https://github.com/Itseez/opencv/blob/2.4/modules/video/src/tvl1flow.cpp#L142

tau            = 0.25;
lambda         = 0.15;
theta          = 0.3;
nscales        = 5;
warps          = 5;
epsilon        = 0.01;
iterations     = 300;
useInitialFlow = false;
