Abstract—Neuromorphic accelerators are emerging as a potential
solution to the growing power demands of Artificial
Intelligence (AI) applications. Spiking Neural Networks (SNNs),
which are bio-inspired architectures, are being considered as a
way to address this issue. Neuromorphic cameras, which operate
on a similar principle, have also been developed, offering low
power consumption, microsecond latency, and robustness in var-
ious lighting conditions. This work presents a full neuromorphic
system for Computer Vision, from the camera to the processing
hardware, with a focus on object detection. The system was
evaluated on a compiled real-world dataset and a new synthetic
dataset generated from existing videos, and it demonstrated good
performance in both cases. The system was able to make accurate
predictions while consuming 66mW, with a sparsity of 83%, and
a time response of 138ms.

In this work, we implemented an end-to-end fully neuro-
morphic object detector using an event-based DVXplorer Lite
sensor by Inivation [14] and event-based processor Akida by
Brainchip [15]. The detector is based on an AkidaNet [16]
backbone, designed by Brainchip and optimized for Akida
chip, and a YOLOv2 [17] detection head, whose structure is
suitable to the Akida constraints. The main purpose of this
work is to show the potential of a full-spiking system by
creating an object detector with a small memory footprint, low
power consumption, and real-time response. The contributions
of this work are as follows (a) implementation of the first end-
to-end Akida-based full-spiking system for object detection
in the literature. To the best of our knowledge, there is
only one work implementing object detection on an actual
spiking platform, implemented over a SpiNNaker 3 [12].
(2)Generation of a new synthetic event-based dataset based
on recordings of traffic junctions; and (3) Evaluation of the
system’s performance, power consumption, and time-response,
showing that it can perform real-time detections with low
power consumption.
For Object Detection in SNNs, there is a lack of data reported for such
measures in actual spiking setups, where the only results
reported up to now are from Attention RPN-SNN [12]. In
that work, a SpiNNaker 3 neuromorphic chip wasdeployed
for detection tasks, reporting a totalprocessing time of 35.3s
and power of 600mW.
VI.CONCLUSION AND FUTURE WORK
This work showed a low-power and real-time latency full
spiking neuromorphic system for object detection based onIni-
Vation’s DVXplorer Lite event-based camera and Brainchip’s
Akida AKD1000 spiking platform. The system was evaluated
on three different datasets, comprising real-world andsynthetic
samples. The final mapped model achieved mAPs of 28.58 for
the GEN1 dataset, equivalent to 54% of a more complex state-
of-the-art model and 89% of the performance detection from
the best-reported result for the single-class dataset PEDRo,
having 17x less parameters. A power consumption of 66mW
and a latency of 138.88ms were reported, being suitable for
real-time edge applications.
For future works, different modelsare expected to be
adapted to the Akida platform,from which more recent
releases of the YOLO family can beimplemented. Moreover,
it is expected to evaluate thosemodels in real-world scenarios
instead of recordings, as well asthe acquisition of more data
to evaluate this setup underdifferent challenging situations.
