Experimental Comparison between Event and Global Shutter Cameras
Sensors, 2021 We compare event-cameras with fast (global shutter) frame-cameras experimentally, asking: “What is the application domain, in which an event-camera surpasses a fast frame-camera?” Surprisingly, finding the answer has been difficult.

Event-Based Camera Tracker by ∇
IEEE Access, 2023 When a camera travels across a 3D world, only a fraction of pixel value changes; an event-based camera observes the change as sparse events. How can we utilize sparse events for efficient recovery of the camera pose?
