| 摘 要： | 目的为重建和测量髋臼的解剖结构,需要大量地读取CT图像的信息,以获得髋臼轮廓的坐标值。方法本研究采用直方图阈值图像分割、kirsh边缘提取法获得髋臼的二值化轮廓图像。轮廓坐标的提取应用了“迷宫”边缘跟踪算法。结果本方法可大量、快捷、正确的提取图像轮廓信息。

| Abstract: | Objective In order to reconstruct and measure anatomic structure of acetabulum, a lot of information in the CT image were required to detect the aetabulum contour coordinate. Methods The algorithm of histogram-threshold segmenting and Kirsh boundary detection were employed for making a binary contour image. The coordinate of contour were detected by "maze" boundary tracking algorithm . Results This approach could process the information of image contour in the manner of large scale, rapid process and less error. |
