- Abstract: Dynamic vision sensor event cameras produce a variable data rate stream of
brightness change events. Event production at the pixel level is controlled by
threshold, bandwidth, and refractory period bias current parameter settings.
Biases must be adjusted to match application requirements and the optimal
settings depend on many factors. As a first step towards automatic control of
biases, this paper proposes fixed-step feedback controllers that use
measurements of event rate and noise. The controllers regulate the event rate
within an acceptable range using threshold and refractory period control, and
regulate noise using bandwidth control. Experiments demonstrate model validity
and feedback control.

Event-based vision sensors produce an asynchronous stream of events which are triggered when pixel intensity variation exceeds a threshold.
We propose an approach for dynamic feedback control of activation thresholds, in which a controller network analyzes the past emitted events.
We demonstrate that our approach outperforms both fixed and randomly-varying threshold schemes by 6-12% in terms of LPIPS perceptual image dissimilarity metric.

Event cameras are increasingly popular in robotics due to beneficial features such as low latency, energy efficiency, and high dynamic range.
These parameters regulate the necessary change in light intensity to trigger an event, which in turn depends on factors such as the environment lighting and camera motion.
This paper introduces feedback control algorithms that automatically tune the bias parameters through two interacting methods.
