Interactive Medical Image Segmentation Using Snake and Multiscale Curve Editing
Figure 11
Tracking the boundary of the left lung in consecutive axial slices by the proposed method in 3D volumes. (a) Slice number 109, (b) slice number 108, (c) slice number 107, and (d) slice #106. The left column shows the original lung images in consecutive axial slices. The middle column shows the initial contour in corresponding axial slices. The right column shows the zoomed images of final contours obtained by the snake model (blue) and the multiscale curve editing (green, two levels). Note that the initial contour is only manually drawn in slice #109. The initial contour of other slices will be the final contour of its consecutive slice that has been delineated. For instance, the final contour of #109 will be the initial contour of slice number 108.
