Speech Title:Near-sensor and in-sensor computing for neuromorphic machine vision


Neuromorphic visual systems have considerable potential to   emulate basic functions of the human visual system even beyond the visible   light region. However, the complex circuitry of artificial visual systems   based on conventional image sensors, memory and processing units presents   serious challenges in terms of device integration and power consumption. Here   we show simple two-terminal optoelectronic resistive random access memory   (ORRAM) synaptic devices for an efficient neuromorphic visual system that   exhibit non-volatile optical resistive switching and light-tunable synaptic   behaviours. The ORRAM arrays enable image sensing and memory functions as   well as neuromorphic visual pre-processing with an improved processing   efficiency and image recognition rate in the subsequent processing tasks. The   proof-of-concept device provides the potential to simplify the circuitry of a   neuromorphic visual system and contribute to the development of applications   in edge computing and the internet of things.
