该程序主要用于车型识别，利用两幅图像相减进行提取轮廓，然后再通过计算定长和车底的比进行判断车型。

基于组相似的活动轮廓模型，Active Contours with Group Similarity，该源码是CVPR2013年中一篇文章的matlab代码，能够自动提取相似目标的公共形状，具有一定的参考价值。-Group similar to the active contour model based on, active contours with group similarity, the source code is CVPR2013 years in an article in th

比较了几种常用的提取轮廓线的算子，例如，sobel算子，roberts算子，log算子等。-Several commonly used operators to extract contour lines are compared, such as Sobel operator, Roberts operator, LOG operator, etc.
