基于图像灰度的纸病检测方法的研究

THE STUDY OF PAPER'S DEFECT INSPECTION METHOD BASED ON IMAGE GRAY SCALE

应用图像处理技术研究了纸张灰度图像的基本特征和分布特征,结果表明纸张的灰度数值是随机的,质量好的纸张灰度分布范围小,且灰度值较高;应用图像灰度分析技术可有效地提取出纸病的特征。

Based on the image processing technology, basic and distribution feature of the paper's gray scale image have been studied. The gray scale value is random. The high quality paper's image histogram distributing range is small and its gray scale value is high. Depending on the gray scale threshold, the feature of the paper's defects have been extracted. The results proved that this method is effective to extract paper's defect feature.
