Fast border marching algorithm:automatic lung segmentation on chest CT images
快速边界行进算法：一种CT图像肺实质自动分割策略*

This paper presented an automatic lung segmentation algorithm called fast border matching algorithm to extract lung parenchyma,revising the segmentation defects caused by juxtapleural nodules.Fast border matching algorithm firstly used some typical methods to extract lung parenchyma,such as Gaussian smoothing,gray-level thresholding,FloodFill non-lung region,etc.Then,introduced Douglas-Peucker algorithm to extract key points from the border of the lung parenchyma.Lastly,it employed adaptive border marching ...
