Contour Propagation Using Feature-Based Deformable Registration for Lung Cancer
Figure 5
Comparison between fully automatic segmented methods and the manual delineation. The cyan contours were manual delineated contours. (a) Flood fill algorithm (yellow); (b) active contour (red); (c) watershed algorithm (blue). The region embraced by the black ellipse failed to be delineated by these automatic segmentations.
