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), thr

形状是由图像的轮廓形成的，所以理论上形状识别是通常在边缘或轮廓检测后的步骤。(edge_based_matching The shape is formed by the outline of the image, so theoretically the shape recognition is usually the step after the edge or contour detection)

非常有用的资料，C#源码,能够直接导入DXF文件，并对DXF文件分析是圆、线，轮廓等形状，并对形状进行分析，可以直接生成G代码或者点位信息。自己可以拿点位信息再做处理。(Very useful information, C # source code, can directly import DXF file, and DXF file analysis is circular, line, contour and other shapes, and shape analysis, can di

选取几幅同类目标物体的二维图像，并标注轮廓点，不断迭代，寻找标准形状，利用最小二乘法寻找每个样本形状到这个标准形状的变化，校正去噪。(Select several two-dimensional images of similar objects, mark the contour points, iterate continuously, find the standard shape, use the least square method to find the change of eac
