| 摘 要： | 基于活动轮廓模型的分割广泛应用于医学图像，提出了一种两步活动轮廓模型算法用于核磁共振脑部图像中侧脑室的分割。首先用传统活动轮廓模型求解，然后采用遗传算法进行优化，得到了较好的结果，解决了一般活动轮廓模型对侧脑室的尖锐角点处分割效果不理想的问题。

| Abstract: | Active model-based segmentation has frequently been used in medical image processing. The author introduces a new two-step active model-based algorithm for lateral ventricles segmentation in MRI. It uses traditional snake model for segmentation in the first step, then uses genetic algorithm to optimize. The approach is advanced for segmentation in sharp angular point, and experimental result is satisfied. |
