| 摘 要： | 提出了一种低形状失真度的VSnakes算法。定义了两项新的能量表达式,其中一项使得轮廓控制点的分布更均匀,另一项增强了对候选轮廓曲率的约束,使其不仅仅保持与当前轮廓的形状相似,而且轮廓曲线更加平滑,从而降低了最终收敛轮廓的形状失真度。同时对轮廓松弛过程进行了简化,降低了算法复杂度。

| Abstract: | A low shape distortion algorithm for VSnakes was presented. Two new energy expressions were defined, one of them spaced the points more evenly on the contour,the other expression strengthened the curvature constraint of the candidate contour, which not only kept its shape similar to the current contour, but also made contour more smooth, thus reduced the shape distortion of contour. In addition, the contour-relaxation process was simplified to reduce the complexity of computation. |
