摘    要: 针对棉/亚麻混纺纤维构成的织物,基于其单纤维纵向显微图像(纤维切段的长度约为0.5mm),研究了纤维的自动识别方法。在纤维检测中,先对纤维图像进行去背景处理,而后运用形态学闭运算和背景区域生长相结合的方法获得纤维的目标区域,对图片中出现的玻璃划痕、干扰杂物等进行了很好的滤除。由纤维骨架垂直方向上的区域图、二值图和细化图得到它们的垂直积分投影序列,并提取这3条序列各自的变异系数CV值和平均值共计6个参数。将这6个参数作为棉/亚麻纤维的特征参数,训练最小二乘支持向量机分类器,对测试集的测试结果表明该分类器对棉/亚麻短纤维的识别率正确率平均为93.3%。

关 键 词:棉纤维  亚麻纤维  纵向切段  混纺比  检测  图像识别  特征提取  支持向量机

Abstract:Aiming at cotton/flax blended fabrics,a new automatic identification method based on the longitudinal view of microscopic fiber images is proposed,in which the length of fiber about 0.5 mm is used for image capture.For fiber detection,the background of fiber image is removed firstly,then fiber areas are detected by a method combining morphological close operation and background regional growth,and the glass scratches and other sundries in the images are filtered as well.Based on the region image,binary image and refining image of binary image perpendicular to the fiber skeleton,their vertical integral projection series are captured,and each coefficient variation(CV value) and mean value of these three series are extracted and used as the texture parameters of cotton/flax blended fabric to train the least square support vector machine classifier.The experiment results show that the mean identification accuracy of cotton and flax fibers is 93.3%.
Keywords:cotton fiber  flax fiber  longitudinal view  blending ratio  detection  image recognition  feature extraction  support vector machine
