Interactive Medical Image Segmentation Using Snake and Multiscale Curve Editing
Figure 5
A hierarchical multiscale approach to generate uniformly spaced control points for manual editing: (a) first level with 13 control points, (b) second level with 25 control points, (c) third level with 50 control points, and (d) fourth level with 100 control points. White cross shows the uniformly spaced control points. Red color shows the contour obtained from the snake model, and blue color shows the curve generated by Hermite cubic curve with associated control points.
