Memory Efficient Corner Detection for Event-driven Dynamic Vision Sensors

no code implementations18 Jan 2024 Pao-Sheng Vincent Sun, Arren Glover, Chiara Bartolozzi, Arindam Basu

In this paper, we propose a new event-driven corner detection implementation tailored for edge computing devices, which requires much lower memory access than luvHarris while also improving accuracy.

WaLiN-GUI: a graphical and auditory tool for neuron-based encoding

no code implementations25 Oct 2023 Simon F. Müller-Cleve, Fernando M. Quintana, Vittorio Fra, Pedro L. Galindo, Fernando Perez-Peña, Gianvito Urgese, Chiara Bartolozzi

Neuromorphic computing relies on spike-based, energy-efficient communication, inherently implying the need for conversion between real-valued (sensory) data and binary, sparse spiking representation.

Constraints on the design of neuromorphic circuits set by the properties of neural population codes

no code implementations8 Dec 2022 Stefano Panzeri, Ella Janotte, Alejandro Pequeño-Zurro, Jacopo Bonato, Chiara Bartolozzi

In the brain, information is encoded, transmitted and used to inform behaviour at the level of timing of action potentials distributed over population of neurons.

PUCK: Parallel Surface and Convolution-kernel Tracking for Event-Based Cameras

no code implementations16 May 2022 Luna Gava, Marco Monforte, Massimiliano Iacono, Chiara Bartolozzi, Arren Glover

ATIS + SpiNNaker: a Fully Event-based Visual Tracking Demonstration

no code implementations3 Dec 2019 Arren Glover, Alan B. Stokes, Steve Furber, Chiara Bartolozzi

The Asynchronous Time-based Image Sensor (ATIS) and the Spiking Neural Network Architecture (SpiNNaker) are both neuromorphic technologies that "unconventionally" use binary spikes to represent information.

Event-based Vision: A Survey

4 code implementations17 Apr 2019 Guillermo Gallego, Tobi Delbruck, Garrick Orchard, Chiara Bartolozzi, Brian Taba, Andrea Censi, Stefan Leutenegger, Andrew Davison, Joerg Conradt, Kostas Daniilidis, Davide Scaramuzza

Event cameras offer attractive properties compared to traditional cameras: high temporal resolution (in the order of microseconds), very high dynamic range (140 dB vs. 60 dB), low power consumption, and high pixel bandwidth (on the order of kHz) resulting in reduced motion blur.
