| 摘 要： | 本文提出一种基于局部与全局特征的活动轮廓模型左心室MR图像分割算法.该算法融合了图像局部信息和全局信息.局部信息包含了图像局部均值和方差信息,来克服图像灰度不均匀的影响.全局信息则较好地提高模型处理图像弱边界的能力,并防止模型陷入局部最优,实验结果表明,改进算法分割出较为精确的心脏左心室MR图像.

| Abstract: | Left ventricle MRI segmentation active contour model based on local and global features was presented in this paper.The local fitting term contained means and variances of local region,overcame the influence of intensity inhomogeneities.The global intensity fitting term,which conquered the unexpected local minimum stemming from image local intensity and deals with weak.The experiment results demonstrate that the algorithm is effective for segmenting the left ventricle MR images. |
