Differentiating between birds and drones is a huge problem at civilian and military airfields and facilities. Bézier curves are a powerful tool to differentiate between the fixed angles of a drone and the deformable or variable angles of a bird flapping its wings.

As demonstrated below, Vy’s technology is particularly effective differentiating between natural and man-made objects at low resolution.
