摘要
应用基于Wold纹理模型,从织物纹理中提取非确定性随机结构.通过正常纹理和疵点纹理中随机结构的表面维分形特征曲线比较,以距离为判别标准定位疵点.几种典型织物疵点的分析表明,基于Wold纹理模型和分形理论的分析方法能准确地检测出织物表面的多种疵点.
Wold - based texture model is applied to extract the indeterministic field in the fabric texture, then characteristic curve of area fractal dimension is calculated. By comparison of the characteristic curve between normal fabric texture and defects fabric texture, the defects can be detected with the characteristic curve distance. After analysing several typical samples, it can be concluded that many fabric defects can be detected with the method combining the Wold - based texture model and fractal theory.
