1. 线性相关(Linear Cross-Correlation)的定义和计算 假设我们手里有两组数据,分别为 个和 个,表示为: 和 , 比 长,即 。序列 和 之间的线性互相关操作表示为 ,其结果也是一个序列,表示为 。具体的操作是用这两个序列进行的一种类似“滑动点积”的操作,如图1和图2所示。
1. An optical flow method instead of the cross correlation method is proposed for convective precipitation system. 针对强对流降水的情况,提出了使用光流法计算得到的光流场来代替交叉相关法得到的运动矢量场。更多例句>> 2) method of time_delay cross correlation 延时交叉相关法...
The crosscorrelation function is seen in Figure 2.18B. While the time at which the peak occurs is difficult to determine visually due to the large scale of the horizontal axis, the peak is found to be 0.013 sec using the method described above. The maximum correlation at this lag is 0.45...
[3] the authors has proposed a method of medical image registration by template matching based on Normal ized Cross-Correlation (NCC) using Cauchy-Schwartz i nequal ity. They have i mplemented the algorithm for template matching using NCC in MATLAB.The developed algorithm was robust for simi ...
Cross-correlation is a measurement used in statistics. It is a method of measuring the relative degree of similarity or dissimilarity between two variables. How Is Cross-Correlation Useful? Consider a stock investor who owns a technology stock that has been performing well. The investor might want...
