| 摘 要： | 研究和分析了形态学梯度算子，提出了一种适合X射线数字图像边缘检测的多尺度形态学梯度算子；这种算子的取值来自于膨胀梯度图和腐蚀梯度图中同位置像素的最小值，它结合了膨胀和腐蚀的优点。也考虑了X射线数字图像对比度低的特点；实验证明这是一种检测X射线数字图像边缘的有效方法。

| Abstract: | Morphological gradient operator is researched and analyzed, a new multistage morphological gradient operator is presented, which is fit for edge detecting of X- ray digital image. The operator comes from the minimum of the same position pixel between eroded gradient image and dilated gradient image, it combined the virtue of erosion and dilation, and gave attention to the low contrast of X--ray digital image. Simulation results indicated that the edge detection on X--ray data image is a effective method. |
