SciDVS: A Scientific Event Camera with 1.7% Temporal Contrast Sensitivity at 0.7 lux

Rui Graca, Sheng Zhou, Brian McReynolds +1

This paper reports a Dynamic Vision Sensor (DVS) event camera that is 6x more sensitive at 14x lower illumination than existing commercial and prototype cameras. Event cameras outp…

Re-Interpreting the Step-Response Probability Curve to Extract Fundamental Physical Parameters of Event-based Vision Sensors

Brian McReynolds, Rui Graca, Lucas Kulesza +1

Biologically inspired event-based vision sensors (EVS) are growing in popularity due to performance benefits including ultra-low power consumption, high dynamic range, data sparsit…

Optimal biasing and physical limits of DVS event noise

Rui Graca, Brian McReynolds, Tobi Delbruck

Under dim lighting conditions, the output of Dynamic Vision Sensor (DVS) event cameras is strongly affected by noise. Photon and electron shot-noise cause a high rate of non-inform…

Exploiting Alternating DVS Shot Noise Event Pair Statistics to Reduce Background Activity

Brian McReynolds, Rui Graca, Tobi Delbruck

Dynamic Vision Sensors (DVS) record "events" corresponding to pixel-level brightness changes, resulting in data-efficient representation of a dynamic visual scene. As DVS expand in…

Shining light on the DVS pixel: A tutorial and discussion about biasing and optimization

Rui Graça, Brian McReynolds, Tobi Delbruck

The operation of the DVS event camera is controlled by the user through adjusting different bias parameters. These biases affect the response of the camera by controlling - among o…

Utility and Feasibility of a Center Surround Event Camera

Tobi Delbruck, Chenghan Li, Rui Graca +1

Standard dynamic vision sensor (DVS) event cameras output a stream of spatially-independent log-intensity brightness change events so they cannot suppress spatial redundancy. Nearl…
