由于受到织物表面附着有细小绒线、结头、灰尘等材质以及成像噪声的影响,织物图像的纹理特性在一定程度上被模糊,给织物缺陷检测带来了困难。针对上述问题,文章提出了一种基于纹理增强分水岭的织物瑕疵检测新算法。该算法首先利用非局部均值滤波实现纹理增强,消除成像噪声及材质的影响,有效地突出了纹理间的差异。在此基础上,进一步利用纹理分水岭方法,提取缺陷区域;通过对一组纺织品缺陷检测的实验结果表明,该算法能够准确地提取出纺织品的缺陷区域,实现纺织品缺陷检测。
由于受到織物錶麵附著有細小絨線、結頭、灰塵等材質以及成像譟聲的影響,織物圖像的紋理特性在一定程度上被模糊,給織物缺陷檢測帶來瞭睏難。針對上述問題,文章提齣瞭一種基于紋理增彊分水嶺的織物瑕疵檢測新算法。該算法首先利用非跼部均值濾波實現紋理增彊,消除成像譟聲及材質的影響,有效地突齣瞭紋理間的差異。在此基礎上,進一步利用紋理分水嶺方法,提取缺陷區域;通過對一組紡織品缺陷檢測的實驗結果錶明,該算法能夠準確地提取齣紡織品的缺陷區域,實現紡織品缺陷檢測。

The texture property of fabric image is affected by the fine knitting yarn ,rolling and dust at-tached on the surface of fabric product as well as imagery noise ,which will cause the texture property of fabric image to be blurred to some extent .This makes the fabric defect detection more difficult .To solve this problem ,a new method for fabric defect detection based on texture enhancement and water-shed is proposed in this paper .In this method ,the texture enhancement can be achieved by using the nonlocal means(NL-means) filter ,so the effect of imagery noise and materials is eliminated and the difference between the defect texture and background texture can be obviously enhanced .Combined with the watershed transform ,the defect regions in fabric images can be detected accurately .The ex-perimental result show s that the proposed method achieves efficient and accurate performance on the detection of fabric images containing fabric defects .
