摘    要:提出了利用分形几何的盒子维数检测焊缝图像边缘的方法,分析并比较了各种计算盒子维数方法的优缺点,利用焊缝X射线图像进行实验,结果证明差分盒维法(DBC)检测焊缝边缘效果较好,能得到单一、连续的焊缝边缘和其内包含的缺陷边缘。

关 键 词:分形维数  差分盒维数  图像处理  边缘检测

Abstract:A fractal box dimension method was proposed to detect edge of weld,which was compared with other box dimension calculation methods.X rays pictures was used to test the methods.The experimental results prove that the differential box-counting(DBC) is better than other methods.Single,continuous weld edge and inner defects edge were got.
Keywords:fractal dimension  differential box-counting(DBC)  image processing  edge detection
