A Computer-Aided Pipeline for Automatic Lung Cancer Classification on Computed Tomography Scans

Figure 1

Work flow of the designed pipeline to detect lung cancer. The system consists of four stages: Stage I—enhancement of lung CT image and a novel lung volume segmentation method (LUVEM), Stage II—candidate nodule detection using CHT and segmentation of lung nodules using SOM, Stage III—computing of lung nodule features and reduction features using PCA, and Stage IV—classification of malign and benign lung nodule using PNN.
