Description: Based on the information processing functionalities of spiking neurons, a spiking neural network model is proposed to extract features from a visual image. The network is constructed with a conductance-based integrate-and-fire neuron model and a set of specific receptive fields. The properties of the network are detailed in this paper. Simulation results show that the network is able to perform image feature extraction within a time interval of 100 ms. This processing time is consistent with the human visual system. The demonstrations show how the network can extract right-angle contours in a visual image. Based on this principle, many other image features can be extracted by analogy. The parallel processing mechanism of this network model is very promising for a hardware implementation based on VLSI or FPGA technology. Platform: |

Description: 我们给leaky integrate-and-fire neuron 的概述。引入的漏水整合和火神经元可能是一个正式的leaky integrate-and-fire neuron 的最有名的例子。leaky integrate-and-fire neuron 的推广包括leaky integrate-and-fire neuron 。所有的leaky integrate-and-fire neuron 可以通过外部电流或从突触前神经元突触输入刺激。-we give an overview of integrate-and-fire models. The leaky integrate-and-fire neuron introduced is probably the best-known example of a formal spiking neuron model. Generalizations of the leaky integrate-and-fire model include the nonlinear integrate-and-fire model. All integrate-and-fire neurons can either be stimulated by external current or by synaptic input presynaptic neurons. Platform: |
