| 摘 要： | 目标检测中模板匹配常需用掩膜排除待匹配窗口中的一些不相关区域.模板匹配的相关算法计算过程十分耗时,但由于掩膜的区域往往不规则,适用的快速算法较少.提出广义掩膜积分图像,实现了一种有掩膜的快速模板匹配算法.该算法不仅只需遍历待匹配窗口和模板的像素一次,而且在不改变匹配精度的同时简化了计算过程.人脸检测实验证明,该算法能显著提高有掩膜的模板匹配计算效率,特别适于需对目标和模板进行整体与局部多次匹配的应用场合.

| Abstract: | It is often needed for template matching to eliminate some irrelevant areas of the matching window with mask in object detection. The computing process of template matching with correlation algorithm is very time consuming,few of the fast algorithm can be used to solve this problem as the areas of mask is often irregular. The extended integral image with mask is proposed,and a fast template matching algorithm is realized with it. This algorithm only need to ransack all pixels in the matching window one time... |
