为提高侧脑室分割的准确性和鲁棒性,提出了一种改进的梯度矢量流(Gradient Vector Flow,GVF)Snake算法用于侧脑室的分割。该算法首先运用先验信息自动化初始化轮廓线;其次通过边界检测算子对脑影像处理生成边缘图;最后在边缘图的基础上计算GVF场,并进行轮廓线演化得到侧脑室分割结果。选取不同特征的侧脑室图像对该算法进行实验验证,该算法能准确提取侧脑室尖锐角点处轮廓,克服了GVF S
In Comparison with the traditional point-by-point line generation method,the methodwe present is based on segment code in Pan-Euclidean geometric space and is q
