Description: 图像分割是由图像处理到图像分析的关键步骤，涉及到计算机视觉技术的复杂问题。在医学图像方面，许多应用大都依赖于对图像中目标轮廓的准确提取。基于微分算子检测的方法几乎都对噪声较为敏感且不能保证得到连续的边缘，无法用于辨识和分析目标。由Kass提出的基于主动轮廓线的Snake模型[1]，用一个具有一定弹性的封闭曲线，在曲线自身形状约束力和由图像数据计算而来的外部力的共同作用下演化，来逼近目标边界，完成对图像的分割。
GVF snake VC++做的-Image segmentation by image processing to image analysis of the key steps involved in computer vision technology to complex problems. In medical images, many applications largely depends on the target images extracted contour accuracy. Based on the differential operator method of detecting almost all more sensitive to noise and can not guarantee that they will get straight edge, can not be used for target identification and analysis. Kass raised by the active contour based on the Snake model [1], with a certain flexibility of the closed curve in the curve shape their own binding and calculated by the image data from the external force under the joint effect of the evolution of the boundary to approximate the target , completion of the image segmentation. GVF snake VC++ Make the

Description: This case study shows how MATLAB can be used for a medical imaging problem. Given an MRI scan, first segment the brain mass from the rest of the head, then determine the brain volume. Also compare portions of gray and white matter present. This example was developed for seminars. It was also used for webinars for medical applications broadcast live on May 6, 2004.
This package includes some MATLAB code and an MRI scan series consisting of 60 DICOM images. Note that this code relies on MATLAB Central submissions from others. Detailed references to those sources are included.

Description: 人工干预使蛇模型只能用于半自动的图像分割，该文在梯度向量流(GVF)蛇模型的基础上提出一种基于流场节点与最小路径方法
的全自动图像分割算法。在图像的GVF 场上检测出流场节点，以节点为种子，采用多标记快速扫描法获得一个初始分割，采用区域合并
得到最终分割结果。实验结果证明了该算法的鲁棒性和有效性。-Manual intervention to make the snake model can only be used for semi-automatic image segmentation, the text in the gradient vector flow (GVF) snake model based on the flow field based on the node with the smallest path method of automatic image segmentation algorithm. GVF field in the images to detect the flow field in node to node for the seeds, the use of many markers rapid scanning method to obtain an initial segmentation, the use of regional segmentation results eventually be merged. The experimental results show that the algorithm robustness and effectiveness.
