【摘要】 本文针对织物组织具有一定二维周期性的特点,利用微机图象处理方式,采用二维谱分析和自相关分析方法,揭示了简单组织的功率谱和自相关函数的分布特征与对应关系,给出了刻划织物组织空间周期性的一组特征参数.它为自动识别织物组织提供了依据,也为图象处理应用于检测织物性能和组织结构打下了基础.更多还原

【Abstract】 In this paper,the sampling method and process for the fabric texture images by use of CCD camera and A/D device are described. Since textile patterns have periodic nature,the 2 -D Fourier power spectrum, the 2 -D autocorrelation function are selected as recognition and analysis tools. Ideal models of plain and twill are suggested. Also,some characteristics of the Fourier power spectrum and the autocorrelations are revealed.更多还原
