| 摘 要： | 基于Level Set方法,提出了一种应用于对低对比度医学图像进行分割的改进的FastMarching方法.该方法结合演化曲线在演化过程中平均能量的变化特性,重新定义Fast Marching算法的停止准则,从而提高了算法的鲁棒性和自动性.实验结果表明,所提出算法的分割效果良好.

| Abstract: | Based on Level Set method,an improved Fast Marching method was presented to segment low contrast medical images.Combined with the characteristic of the advancing front's average energy when the curve evolving,the stop criterion of Fast Marching method was redefined.The experimental results show that this improved algorithm can enhance the robustness and automation of Fast Marching method. |
