    • An image processing method for extracting a thread-like structure (GW) represented on the background in a digital noisy original image (IM1), comprising steps of acquisition (1) of the original image data; extraction (2) of elementary pixel strings (A1,A2,.) associated in string sets (SA,SB,SC), each of a same threadlike structure, forming a string set image (IM2); operation (4) of a First Phase (Intra-Set Phase) automatically yielding one Best String (A,B,C) per string set (INSI); and/or operation (5) of a Second Phase (Extra-Set Phase) automatically yielding one Final Best String (FBS) by linking Best Strings or elementary strings when the Second Phase is directly carried out (EXSI), for representing the threadlike structure (GW). Application: Medical Imaging; X-ray apparatus with image processing means and display means.
    • 一种用于提取在数字噪声原始图像(IM 1)中在背景上表示的线状结构(GW)的图像处理方法,包括以下步骤:获取(1)原始图像数据; 提取(2)与字符串组(SA,SB,SC)相关联的基本像素串(A 1,A 2,...),每个相同的线状结构,形成字符串集合图像(IM 2); 第一阶段(内部设置阶段)的操作(4)自动产生每个字符串集(INSI)的一个最佳字符串(A,B,C); 和/或第二阶段(额外设置阶段)的操作(5)通过在直接执行第二阶段(EXSI)时链接最佳字符串或基本字符串来自动产生一个最终最佳字符串(FBS),用于表示线状结构 (GW)。 应用:医学影像; 具有图像处理装置和显示装置的X射线装置。
