说明：  Snake是提取物体精确轮廓常用的算法,自Kass于1987年提出以来，已广泛应用于数字图像分析和计算机视觉领域。由于SNAKE模型具有良好的提取和跟踪特定区域内目标轮廓的能力，因此非常适合于医学图像如CT和MR图像的处理，以获得特定器官及组织的轮廓。Matlab编写。
(Snake is the precise object contour extraction algorithms commonly used, since Kass in 1987 proposed, it has been widely used in digital image analysis and computer vision fields. SNAKE model as a result of good extraction and tracking a specific target region contour, and therefore very suitable for medical images such as CT and MR images of the treatment in order to obtain a specific outline of organs and tissues. Matlab prepared.)
