| 摘 要： | 选取由三种具有典型横截面形状的纤维(兔毛、晴纶和粘胶)组成的混纺纱作为研究对象。经过高通滤波、二值化后,对输入图象进行细化。为了消除存在的孤立点或孤立团,本文对 Hilditch 细化算法作了改进。纤维的轮廓通过以最小夹角原则跟踪获得,然后对轮廓进行平滑并计算其曲率,根据曲率变化以及轮廓内是否有孔洞对纤维进行分类、识别.最后根据识别的结果进行定量分析。

| Abstract: | A blended yarn,spun with rabbit hair,acrylic and viscose fibres,is chosen for the research.TheHilditch algorithm is improved and adopted for image refinement after high-pass-filtering and bina-ryzation.The contour of its cross-section is obtained by tracing its pixels based on the rule of least in-ner angle.The curvature of the contour is then cal culated after smoothing.Classification and recogni-tion of fibres is performed according to variation of their contour curvature and the inner hole of therabbit hair.Results are used for quantitative analysis. |
