| 摘 要： | 本文对C-V主动轮廓模型进行改进.依据曲线演化理论对C-V模型中的图像数据力驱动项进行简化,提出一种常微分方程(ODE)类型的模型.理论分析验证了该模型的水平集函数可初始化为零.与传统C-V模型相比,不但具有其特点,如可以自动检测带孔目标的内轮廓等,而且具有以下优点:抗噪性能较优;水平集函数无需重新初始化,可快速计算出全局最优分割;远离轮廓的边界可以被准确检测;时间迭代步长不受限制.对合成和真实图像的分割结果证明了本文模型具有稳健、快速的优点.

| Abstract: | An improved C-V active contour model was presented,with which the image data force in the C-V model is significantly simplified according to the curve evolution theory.The level set function can be initialized to be zero according to the theory analysis.Distinguished from original C-V model,the level set function of the proposed model is Ordinary Differential Equation(ODE).The proposed model not only has the original C-V model's characteristics,such as the ability of detecting inner edge of the object with ... |
