The particle swarm optimization was applied in BP neural network training. It reasonably confirms threshold and connection weight of neural network, and improves capability of solving problems in realities. Meanwhile, PSO-BP neural network is applied into classification of fabric defect. The method of orthogonal wavelet transform was used to decompose(More)
A lot of function database were built by researching evolution law of uniform stochastic web and quasi-regular patterns mathematical model. It related quasi-regular pattern evolution mechanism with textile pattern design to translate formerly invisible information in mathematic area into visible textile pattern of art design. So the visual field on design(More)
