| 摘 要： | 提出了一种改进的结合基于阈值分割特点的Level Set方法.首先用滤波器对原始图像进行平滑,然后根据当前曲线找到区域的统计特性,最后根据区域之间的统计特性的相似度重新定义了Level Set方法的演化停止准则,从而提高了算法的准确性和自动性.实验结果表明,该方法具有较好的分割效果和较高的分割效率.

| Abstract: | Based on threshold segmentation,an improved Level Set method is presented.First,the original image is smoothed by using filter.Then the regions statistics of the current curve is found.Finally,the stop criterion of Level Set method is defined based on the statistical similarity degree of the regions.The experimental results show that this improved algorithm can enhance the automation of Level Set method and obtain better results. |
