Accuracy and Speed Improvement of Event Camera Motion Estimation Using a Bird’s-Eye View Transformation [PDF]
Sensors, 2022 Event cameras are bio-inspired sensors that have a high dynamic range and temporal resolution. This property enables motion estimation from textures with repeating patterns, which is difficult to achieve with RGB cameras.

Optimization in Visual Motion Estimation. [PDF]
Annu Rev Vis SciSighted animals use visual signals to discern directional motion in their environment. Motion is not directly detected by visual neurons, and it must instead be computed from light signals that vary over space and time. This makes visual motion estimation a near universal neural computation, and decades of research have revealed much about the ...
