用一组可变参数表示目标的可变模板，结合目标图像的边缘信息和模板的边界信息，定义一边缘相关能量函数。利用外部惩罚函数法，建立相关匹配问题的总目标函数，然后用改进的模拟退火（ＳＡ）算法求最佳匹配位置。实验结果显示，这种方案具有良好的匹配效果和较大的应用价值。
A set of variable parameters is used to represent the target’s variable template. An edge-related energy function is defined based on the edge information of the target image and the boundary information of the template. Using the external penalty function method, the total objective function of the matching problem is established, and then the best matching position is obtained by the improved simulated annealing (SA) algorithm. The experimental results show that this scheme has a good matching effect and great application value.
