On spike-timing-dependent-plasticity, memristive devices, and building a self-learning visual cortex
(Frontiers Media, 2011)
In this paper we present a very exciting overlap between emergent nanotechnology and neuroscience, which has been discovered by neuromorphic engineers. Specifically, we are linking one type of memristor nanotechnology ...

AER image filtering architecture for vision-processing systems
(Institute of Electrical and Electronics Engineers, 1999)
A VLSI architecture is proposed for the realization of real-time two-dimensional (2-D) image filtering in an address-event-representation (AER) vision system. The architecture is capable of implementing any convolutional ...

Event-driven sensing and processing for high-speed robotic vision
(Institute of Electrical and Electronics Engineers, 2014)
We present here an overview of a new vision paradigm where sensors and processors use visual information not represented by sequences of frames. Event-driven vision is inherently frame-free, ...

7-decade tuning range CMOS OTA-C sinusoidal VCO
(Institute of Electrical and Electronics Engineers, 1998)
A new operational transconductance amplifier-capacitor (OTA-C) based sinusoidal voltage-controlled oscillator (VCO) has been designed and fabricated, the oscillation frequency of which can be tuned from 74 mHz to 1 MHz. ...

On the use of orientation filters for 3D reconstruction in event-driven stereo vision
(Frontiers Media, 2014)
The recently developed Dynamic Vision Sensors (DVS) sense visual information asynchronously and code it into trains of events with sub-micro second temporal resolution. This high temporal precision makes the output of these ...

A bioinspired 128x128 pixel dynamic-vision-sensor
(2011)
This paper presents a 128x128 dynamic vision sensor. Each pixel detects temporal changes in the local illumination. A minimum illumination temporal contrast of 10% can be detected. A compact preamplification stage has ...
