Pedestrian Detection and Tracking Using a Dynamic Vision Sensor

Computación y Sistemas, 2018
Neuromorphic sensors such as the DynamicVision Sensor (DVS) emulate the behavior of the primary vision system. Its asynchronous behavior makes the data processing easier and faster due to the analysis is only in the active pixels. Pedestrian kinematics contains specific movement patterns feasible to be detected, like the angular movement of arms and ...

HashHeat: A hashing-based spatiotemporal filter for dynamic vision sensor

Integration, 2021
Abstract Neuromorphic event-based dynamic vision sensors (DVS) have much faster sampling rates and a higher dynamic range than frame-based imagers. However, they are sensitive to background activity (BA) events that are unwanted. We propose HashHeat, a hashing-based spatiotemporal BA filter for DVS.

Wide dynamic range vision sensor for autonomous vehicles

Proceedings of 1995 IEEE International Conference on Robotics and Automation, 2002
The dynamic range insufficiency of conventional video cameras is an important problem in realizing robust vision systems for autonomous vehicles. To solve the problem, a method for expanding the dynamic range of video cameras by combining the images taken under different exposure conditions has been developed.

Research on Brain-inspired Vision Based on Dynamic Vision Sensor Cameras

Proceedings of the 2020 International Conference on Aviation Safety and Information Technology, 2020
In this paper, we explored many applications of brain-inspired vision, in which the data was acquired based on a dynamic vision sensor camera, that is PSEE300EVK from French. Specifically, we explored the following three aspects: (1) Converting large-scale artificial convolution neural network into spiking neural network, which can process large-scale ...

Wide dynamic range vision sensor for vehicles

Proceedings of VNIS'94 - 1994 Vehicle Navigation and Information Systems Conference, 2002
The dynamic range of brightness on road scenes is very wide, because the lighting condition dynamically varies with various weather and road conditions. Therefore, the dynamic range of conventional TV cameras is insufficient to input the images of road scenes. The authors have developed a method for expanding the dynamic range of TV cameras. Also, they

Dynamic vision sensor for low power applications

The 18th IEEE International Symposium on Consumer Electronics (ISCE 2014), 2014
This paper presents the design of a dynamic vision sensor for mobile applications. The sensor features a standby mode with less than 250uW of power dissipation. The sensor changes operation mode between standby and normal operation itself depending on input activity.

Observing auroras with dynamic vision sensors

Auroras are a faint space weather light phenomenon caused by the interaction between the solar wind and the Earth’s magnetic field. This interaction can lead to processes that increase the energy of charged particles in the magnetosphere, enabling the particles to enter the ionosphere and cause diffuse or discrete auroras.

Spike Coding: Towards Lossy Compression for Dynamic Vision Sensor

2019 Data Compression Conference (DCC), 2019
Dynamic vision sensor (DVS) as a bio-inspired camera, has shown great advantages in high dynamic range (HDR) and high temporal resolution (us) in vision tasks. However, how to lossy compress asynchronous spikes for meeting the demand of large-scale transmission and storage meanwhile maintaining the analysis performance still remains open.
