Data structure for the representation of a 2D ellipse.
The function PrimitivesDrawer::DrawEllipse draws an ellipse, given its specification in this struct. Other functions (e.g. detectors) can use this struct as well.
| float Ellipse2d::angle |
The rotiation angle of the ellipse, given in radians.
Note that a positive angle will rotate the ellipse clockwise, as the y-axis of the image coordinate system is oriented downward. In the IVt, the rotation angles are consistent for all algorithms/functions that involve rotations.
