Query: Event-based Moving Object Detection and Tracking   Event-based vision sensors, such as the Dynamic Vision Sensor (DVS), are
ideally suited for real-time motion analysis. The unique properties encompassed
in the readings of such sensors provide high temporal resolution, superior
sensitivity to light and low latency. These properties provide the grounds to
estimate motion extremely reliably in the most sophisticated scenarios but they
come at a price - modern event-based vision sensors have extremely low
resolution and produce a lot of noise. Moreover, the asynchronous nature of the
event stream calls for novel algorithms.
  This paper presents a new, efficient approach to object tracking with
asynchronous cameras. We present a novel event stream representation which
enables us to utilize information about the dynamic (temporal) component of the
event stream, and not only the spatial component, at every moment of time. This
is done by approximating the 3D geometry of the event stream with a parametric
model; as a result, the algorithm is capable of producing the
motion-compensated event stream (effectively approximating egomotion), and
without using any form of external sensors in extremely low-light and noisy
conditions without any form of feature tracking or explicit optical flow
computation. We demonstrate our framework on the task of independent motion
detection and tracking, where we use the temporal model inconsistencies to
locate differently moving objects in challenging situations of very fast
motion.
