Abstract
Event-based image feature extraction includes reducing an accumulated magnitude of a leaky integrate and fire (LIF) neuron based on a difference between a current time and a previous time; receiving an event input from a dynamic vision sensor (DVS) pixel at the current time; weighting the received input; adding the weighted input to the reduced magnitude to form an accumulated magnitude of the LIF neuron at the current time; and, if the accumulated magnitude reaches a threshold, firing the neuron and decreasing the accumulated magnitude.
