Snakes模型的基本思想很简单，它以构成一定形状的一些控制点为模板（轮廓线），通过模板自身的弹性形变，与图像局部特征相匹配达到调和，即某种能量函数极小化，完成对图像的分割。再通过对模板的进一步分析而实现图像的理解和识别。(The basic idea of the Snakes model is very simple. It uses some control points that form a certain shape as a template (contour line), through the elastic deformation of the template itself, and matches with the local features of the image, that is, some energy function is minimized, and the image segmentation is completed. Further analysis of the template to realize the understanding and recognition of the image.)
