基于非下采样轮廓波变换和朴素贝叶斯分类器的织物缺陷检测
Fabric defect detection based on NSCT and naive Bayes classifier
摘要
Abstract
In order to detect fabric defects that generated during the production process,the algorithm which combines Naive Bayesian classifier (NBC) and nonsubsampled Contourlet transform (NSCT) is presented.The proposed approach is divided into two phases:the learning phase and detection phase.In the learning phase,sub-blocks of defects and defect-free fabric are extracted,respectively.Firstly,NSCT is used to filter and denoise the image.Then,the mixture of the generalized Gaussian distribution (MoGG) model of each sub-block is extracted,and the Kullback-Leibler divergence (KLD) between the sub-blocks is calculated.Finally,NBC is trained by the obtained data.In the detection phase,the detected image is divided into subblocks.The trained NBC is used to detect the sub-blocks,and the defect detection results are output.Experiment results show that the algorithm of the defect detection has a good effect for the uniform gray and color textured fabric and can detect many kinds of fabric defects.The detection accuracy can reach 97% which can meet demand of industrial production.关键词
