| 摘 要： | 提出一种新的基于GVF Snake、利用局部对比增强(LCE)的超声图像分割方法,并与传统的基于GVF Snake的高斯滤波方法进行比较;最后用最大香农熵等方法评价分割结果。实验结果表明:LCE的图像分割效果明显优于常规方法。

| Abstract: | We proposed a new method of image segmentation called Local Contrast Enhancement(LCE),which is based on the GVF Snake to improve the result of image segmentation.The maximal Shannon entropy was applied to determine the optimal result from the segmented images after LCE was compared to traditional Gaussian-Filter based on the GVF Snake.Experimental results show that the proposed method is more effective than the traditional segmentation model. |
