肺部CT图片分割提取出肺实质：迭代法获取灰度阈值；二值化图像；分区使用纯M语言编写，各个环节都是自己编程解决，没有用Matlab内置的函数，方便改成其他语言代码。-Lung CT image segmentation to extract the lung parenchyma: iterative methods for grayscale threshold binary image partition using pure M language, are all aspects

实现肺实质初始轮廓提取，采用区域连通标记去除肺部气管-Realization of the lung parenchyma initial contour extraction, using regional connectivity mark removal lung trachea

实现肺实质初始分割及采用滚球法（形态学开运算）进行修补肺实质轮廓凹陷。-Achieve initial segmentation and the use of the pulmonary parenchyma ball method (morphological opening operation) to repair the lung parenchyma contour depression.
