Contour Propagation Using Feature-Based Deformable Registration for Lung Cancer

Figure 4

Process of the contour propagation and refinement, from the manual delineation to the final automatic contour. Three images stand for three sets of sequential slices. The cyan lines stand for the manual delineation, the red lines stand for the initial contour by SURF-TPS registration, and the yellow lines stand for the final contour refined by Snake. Yellow contours match the cyan better.
