自己编写的源代码能实现简单的形态学操作，如腐蚀膨胀边界提取-I have written the source code to achieve a simple morphological operations, such as corrosion expansion boundary extraction

对边界进行二次取样源码，用canny等算法提取一次边界后，点数过多，不利于描述形状，用这个代码可以实现二次取样。-The boundary of second sampling source, such as canny extraction algorithm with a boundary, too many points, which describe the shape, use this code can realize the second sampling.

the code for boundary extraction

自编系统的边界特征提取，用于图像处理，方便快捷，代码正确，直接调用-Self boundary feature extraction system for image processing, convenient code is correct, a direct call
