'What does the orientation.flow represent in farnebacks method?
Which is the orientation/angle exactly? Between which vectors?
Is it the angle between the first frame and the second frame?
Solution 1:[1]
Estimating Optical Flow delivers you a displacement matrix in pixels. You get the displacement in the x direction and the displacement in y direction.
A person walking from bottom left to top right might give you a flow mean of x=5 and y = -5. As you got a vector, you can calculate the angle using arctan(5/5) = 45 degrees
