Sistema de reconocimiento de caracteres de alta velocidad basado en eventos

Abstract

Spike-based processing technology is capable of very high speed throughput, as it does not rely on sensing and processing sequences of frames. Besides, it allows building complex and hierarchically structured cortical-like layers for sophisticated processing. In this paper we summarize the fundamental properties of this sensing and processing technology applied to artificial vision systems and the AER (Address Event Representation) protocol used in hardware spiking systems. Finally a four-layer system is described for character recognition. The system is slightly based on the Fukushima´s Neocognitron. Realistic simulations using figures of already existing AER devices are provided, which show recognition delays under 10μs.
