基于变差函数的纺织纹理图像分析

摘要

根据变差函数能反映纹理图像的结构性和随机性这一优点，提出一种针对纺织图像纹理周期性和方向性的分析方法。从水平、垂直和其他方向计算纹理图像的变差函数值，完成纺织纹理图像的周期性和方向性分析。实验结果表明，该分析方法有效地实现了纺织面料纹理图像的周期性和方向性的分析，而且确定的纹理周期与实际纹理周期误差极小。%According to variation function ,which reflects structure and randomness of texture images ,a new method for analyzing the textile texture periodicity and directionality is pro‐posed .The variation function value is calculated from horizontal ,vertical ,and other directions to complete the analysis of periodicity and directionality of the textile texture image .Experimental results show that this method can effectively realize the texture image analysis of periodicity and directionality ,and the period error of the determined and the actual texture image is mini‐m al .
