摘　　要：信号的相关是信息处理一个非常重要的运算方法,特别是在处理随机信号中尤为重要。但一维信号相关的概念比较抽象,难以被学生理解。本文利用图像的相关在一幅图像中寻找模板图像的位置,当相关函数达到最大值时,即认为找到两幅图像的最佳配准位置。通过这个图像配准的应用,相关运算的物理含义十分生动形象,十分便于学生掌握。The signal correlation is one of the most important methods for signal processing,especially for random signals.However,the concept of correlation of 1D signal is too abstract to understand for students.In this paper,the correlation of images is use to find the position of the template image located in another image,and when the function reaching the maximum,the right place is considered as the best one for two images to match.Through the application of the image match,the physical meaning of the correlation is vividly illustrated to facilitate students to master.

关 键 词：相关 图像 配准
