Understand

Dynamic vision sensor (DVS) event camera output is affected by noise, particularly in dim lighting conditions.

A theory explaining how photon and electron noise affect DVS output events has so far not been developed.
Moreover, there is no clear understanding of how DVS parameters and operating conditions affect noise.
There is an apparent paradox between the real noise data observed from the DVS output and the reported noise measurements of the logarithmic photoreceptor.
