摘要
提出了用于对纱线毛羽特征参数提取的多区域轮廓跟踪算法,该算法是在链码法轮廓跟踪算法的基础上,对跟踪方向进行调整,并对已跟踪完成的纱线区域进行区域填充。实验表明,该算法不但可以对任意条纱线进行轮廓跟踪及特征提取,而且得到的边界曲线封闭连续,只有单像素宽,提高了特征提取的效率和精度。
In this paper, a multi-region contour tracking algorithm is presented for yarn hairiness feature extraction. Based on chain code contour tracking, the algorithm adjusts track direction and fills the tracked yarn region. The experiment shows that the algorithm has nothing to do with the number of yarns, and its continuous closed boundary curve is only one pixel wide, which improves the extraction efficiency and accuracy.
