股骨CT图像的边缘提取

A Boundary Tracking Appoach for Femur CT Lmage

为重建和测量股骨的解剖结构 ,需要大量地读取CT图像的信息 ,以获得股骨轮廓的坐标值。本研究采用直方图阈值图像分割、Kirsh边缘提取方法获得股骨的二值化轮廓图像。轮廓的提取应用了“迷宫”边缘跟踪算法。本方法可大量、快捷、正确地提取图像轮廓信息。

To reconstruct and measure anatomic structure of femur,more information in the CT image were detected for acquiring the aetabulum contour coordinate.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.This approach could process the information of image contour in large,rapid and less error.
