对于两个(x和y)随机过程而言,交叉相关性(cross-correlation)这个概念表示的这两个随机过程的相似程度;delta_xy(t') = E[x(t)y(t-t')]。 在某个时间差t‘=T 的时候,发现delta_xy 出现极大值的时候,说明x(t) 和 y(t-T) 的相似性很高。 赞(1) 回复 moody 楼主 2020-09-16 06:24:06 楼上...

Two data sets including the historical geomagnetic field model and the length of the day are used to analyze the correlation characteristics of the geomagnetic field variation and the changes in the length of the day from 1840～2000.The results show that a lag correlation is available in the ch...
To account for the distortion of the signal during its propagation between the two points an optimum time lag can be estimated by the analysis of the cross-correlation of the two time series. This study clarifies the relation between the transit time estimated by the time lag method and the ...

We find a 40 % lower RMSE for the lag-1 autocorrelation function (ACF) for the Gaussian kernel method vs. the linear interpolation scheme,in the analysis of highly irregular time series. For the cross correlation function (CCF) the RMSE is then lower by 60 %. The application of the Lomb...
It is worthwhile to remark that correlation analysis is not used for determining the strength of the link between the two geographical locations: the actual value of is disregarded and only the value of is used, to find regions with the same lag. If the mutual lags among any three regions ...

a correlation threshold of 0.3 was applied during the optimization, meaning that if the cross-correlation coefficient of the overlapped parts of two images was below 0.3, the shift calculation was discarded. Once the positions of all of the tiles were obtained, they were merged into a full-FOV...
