Abstract

A spiking neural network with high precision based on a new RGB-HSV preprocessing model is proposed to solve the problem of low accuracy of spiking neural networks in the field of the classification of visual color features.The proposed network extracts cluster color features by combining the features of the simplicity of RGB color channels and intuitive of HSV color space and enhances the recognition ability.A training method with weight momentum is also proposed based on Tempotron supervised learning rules.The method updates weights with new calculations while some of last weights is retained

so that the convergence of network weights is speeded up and the simulation time is saved.Experimental results show that the classification accuracy of the proposed network is up to 96.21%

and the accuracy reaches about 84% after 6 training iterations.
