Title: 肺部ct图像上的肺裂识别方法
Inventor: PU JIANTAO
IPC: G06T1/00
Filed: 2011-09-01
Abstract: 一种以三维平面拟合为基础，高效、准确地识别CT图像上肺裂的自动检测与分割方法。该方法将CT影像看作是一组三维空间点云，通过将肺部区域划分为一些小的球形细分体，然后利用三维平面拟合方法在这些小的细分体中寻找肺裂平面，从而将具有自由曲面特性的肺裂检测转换为一些平面的检测，明显降低了问题的复杂度。此种方法的优点对噪音或者异常值不敏感。另外，在肺裂检测过程，不同类型的肺裂（即左右肺中的斜肺裂和水平肺裂）的识别通过一个简单的聚类方法自动完成。通过和其他方法进行比较后，这种新发明的方法有非常好的准确性、稳定性和高效性等特点。
