Query: Are High-Resolution Event Cameras Really Needed?   Due to their outstanding properties in challenging conditions, event cameras
have become indispensable in a wide range of applications, ranging from
automotive, computational photography, and SLAM. However, as further
improvements are made to the sensor design, modern event cameras are trending
toward higher and higher sensor resolutions, which result in higher bandwidth
and computational requirements on downstream tasks. Despite this trend, the
benefits of using high-resolution event cameras to solve standard computer
vision tasks are still not clear. In this work, we report the surprising
discovery that, in low-illumination conditions and at high speeds,
low-resolution cameras can outperform high-resolution ones, while requiring a
significantly lower bandwidth. We provide both empirical and theoretical
evidence for this claim, which indicates that high-resolution event cameras
exhibit higher per-pixel event rates, leading to higher temporal noise in
low-illumination conditions and at high speeds. As a result, in most cases,
high-resolution event cameras show a lower task performance, compared to lower
resolution sensors in these conditions. We empirically validate our findings
across several tasks, namely image reconstruction, optical flow estimation, and
camera pose tracking, both on synthetic and real data. We believe that these
findings will provide important guidelines for future trends in event camera
development.
