Researchers have analyzed two features used in event-based corner detection, specifically the eigenvalues of the structure tensor and spatiotemporal density values, proposing they act as motion cues. Their work theoretically examines how these features relate to motion direction and empirically validates their utility through controlled experiments on synthetic data. Integrating these enhanced features into an event-based optical flow network improved accuracy on the real-world DSEC benchmark, particularly in data-scarce scenarios and for lower-capacity models.
