Table 1.

Three criterions to classify EBS.

Criterion	Name	Benefits
Spatial	Spatial contrast (SC)	Reducing spatial redundancies makes it well suited for unsteady lighting conditions.
	Spatial difference (SD)	Cheap
Temporal	Temporal contrast (TC)	Reducing temporal redundancies makes it well suited for uneven lighting conditions.
	Temporal difference (TD)	Easy to implement
Data acquisition	Frame event (FE)	Cheap hardware and easy to implement
	Asynchronous event (AE)	Low latency, requires relatively few computing power

The categories (Spatial) and (Temporal) differentiate between relative contrast and absolute differences. Its flexible and adaptive nature makes relative contrast beneficial in case of unsteady and uneven lightning conditions.
