According to distribution patterns of the maximum principal curvatures changing from small to large, from negative to positive, this paper proposed a maximum principal curvature hill climbing method for the sulcal basins segmentation of the cortical surface. 针对大脑皮层表面最大主曲率从脑沟到脑回由小变大,由负变正的分布规律,提出了一种最大主曲率爬山法来对大脑皮层脑沟盆地进行分割。
This method is simple, fast and effective, and it can extract a complete sulcal ravine for each sulcal region. These extracted sulcal ravines successfully reflect the topology of the cortical surface. 该方法能够简单、快速且有效的对每个脑沟区域提取出一条完整的脑沟基底线,成功的反映出大脑皮层表面的拓扑结构。
This paper presented a hill climbing method based on the maximum principal curvatures to segment the sulcal basins on the cortical surface. 提出了一种基于主曲率爬山法对大脑皮层表面脑沟盆地进行分割的方法。
Based on the smoothed principal curvatures of the cortical surface, we segment sulcal regions and gyral regions of the cortical surface. 基于平滑之后的大脑皮层表面的主曲率,对大脑皮层表面的脑沟区域和脑回区域进行分割。
Experimental results show that this method for the extraction of sulcal ravines is very effective and stability. 实验证明该方法对于脑沟基底线的提取是很有效的方法。
Here we successfully applied the graph-cut image segmentation method to the three-dimensional surface of the cerebral cortex. Experimental results show that the graph-cut method is very effective and fast to the sulcal and gyral regions segmentation of three-dimensional cortical surface. 3. 这里我们成功的将Graph-Cut图像分割的方法运用到三维大脑皮层表面上,实验结果表明Graph-Cut图像分割的方法对三维大脑皮层表面的脑沟和脑回区域分割是非常有效和快速的。
