The flow variable output from estimateFlow function is of type opticalFlow and has all the information. You can access them using the dot (.) operator.
For e.g.
vx = flow.Vx;
vy = flow.Vy;
or = flow.Orientation;
mag = flow.Magnitude;

Which equation is used to compute flow.Orientation?
Is it atan2 or atan2d?
I wanted to know, what are the reference directions (0,90,180,270) in OpticalFlow?
Please help
