中文说明：3D骨架提取的基本算法代码，将4种最常见的算法均包含在内。vc代码实现图像细化作为一种图像预处理技术出现,目的是提取源图像的骨架,即是将原图像中线条宽度大于1个象素的线条细化成只有一个象素宽,形成骨架,形成骨架后能比较容易的分析图像,如提取图像的特征.
English Description：
3D skeleton extraction of the basic algorithm code, the four most common algorithms are included. vc code image thinning as a general image preprocessing technologies emerge, the purpose is to extract the skeleton of the source image that is larger than the original image, the line width of the line one pixel refined into only one pixel wide, forming a skeleton form after the skeleton can be relatively easy to analyze the image, such as extraction of the image feature.
