摘要
针对于MRI图像人类脑部实质的提取,提出结合形态学的基于最小偏态指标阈值分割[3]方法,该方法采用最小偏态指标从人脑MRI图像中自动提取大脑皮层和颅骨及其他非脑成分,结合形态学的处理最终仅保留大脑部分。试验证明该方法简单可行,且效果很好。
Presents an image segmentation based on minimum bias-normal distribution index which is used to extract brain structures from MRI. Finds the skull field by the image segmentation method, extracts the brain field by the morphological method. The method reported is a rapid, convenient and feasible approach for extracting the brain structure from the MRI.
