Contour Propagation Using Feature-Based Deformable Registration for Lung Cancer

Figure 7

Three cases of lung tumor segmentation conducted by our proposed method and the flood fill algorithm, respectively. The tumors are located on the bronchia, hilus pulmonis, and lobe, respectively. The cyan contour represents the manual delineation, the yellow contour is generated by our proposed method, and the red region is generated by flood fill algorithm.
