基于胸部CT图像的肺结节计算机辅助检测 -Computer-aided Detection for Pulmonary Nodules Based on chest CT Images

先大津法计算全局图像的阈值，再用阈值分割找出肺实质区域，再填补肺实质空洞，实现用边界追踪检测肺实质边界的目的(The calculation of the overall image threshold Otsu threshold segmentation first, and then find out the lung parenchyma, and pulmonary parenchyma fill holes, trace detection boundary in the purpo

根据已经得到的肺实质区域检测当中是否含有肺结节(The obtained which has lung parenchymal area comprising detecting whether pulmonary nodules)
