- 一种基于方向信息的鲁棒型Hausdorff距离匹配方法。该方法采用方向信息提取图 像边缘,通过计算边缘匹配率( edge matching rate, EMR)获得候选匹配区域,然后采用修正后的Hausdorff距离构造 相似性测度。实验结果表明,该方法加快了匹配过程,提高了抗噪性能,并能够准确匹配含有遮挡和伪边缘点的图 像,从而解决了基于传统Hausdorff距离匹配方法因噪声点、伪边缘点和出格点而造成的误匹配问题。-Based on the direction of inform

- 在采用二维离散小波变换对织物图像进行分解的基础上，引入了熵的概念，将小波熵作为织物图像的特征值，把熵值看作系统紊乱程度的度量，由此得到织物图像的小波熵特征值，通过与正常织物经过二维小波变换后提取的小波熵值相比较，熵值大者即认为有疵点存在-At the use of two-dimensional discrete wavelet transform decomposition of the fabric image, based on the introduction of the concep

- 数学形态学(Mathematical Morphology)诞生于1964年，是由法国巴黎矿业学院博士生赛拉(J. Serra)和导师马瑟荣，在从事铁矿核的定量岩石学分析及预测其开采价值的研究中提出“击中/击不中变换”， 并在理论层面上第一次引入了形态学的表达式，建立了颗粒分析方法。他们的工作奠定了这门学科的理论基础， 如击中/击不中变换、开闭运算、布尔模型及纹理分析器的原型等。数学形态学的基本思想是用具有一定形态的结构元素去量度和提取图像中的对应形状以达到对图像分析和识别的目的。-Mathem
