Video stabilization by good feature to track, opticalFlowPytLK and median Just example

I have to say. This is only alpha version. First of all, I want to release video stabilization together with noise compensation, where i still have some mainly performance issue.. Secondary in some cases the result is not that good. Lets say, I need to fix better choice of the tracked features to stabiliza image.. 

Secondary, I case that the scene is changing the video is little bit shaky.. Some second order filter or Kalman filter should resolve this easily.
