【摘要】 提出了一种采用Hermite样条曲线拟合方法与主动轮廓模型相结合的方法.采用Hermite样条轮廓曲线作为描述主动轮廓线的基函数,给出了这种轮廓模型的能量表达式,利用动态规划技术实现能量最小化的优化过程.采用传统的主动轮廓模型与本文方法分别对两幅颅脑图像中的病变区域提取轮廓,对比实验结果表明,采用Hermite样条轮廓模型可以取得更加令人满意的效果.更多还原

【Abstract】 An improved method combining Hermite splines curve and ACM is presented in this paper. We choose Hermite splines curve as the basic function of Active Contour and present its energy function. The optimization of energy minimization is performed with the Dynamic Programming technique. The results of extracting contours of focus in two skull images show that Hermite Splines Contour Model is more efficient than traditional ACM.更多还原
