Cross-Correlation Function Thecross-correlation function(XCF) measures the similarity between a time series and lagged versions of another time series as a function of the lag. Consider the time seriesy1,tandy2,tand lagsk= 0, ±1, ±2, …. For data pairs (y1,1,y2,1), (y1,2,y2,2)...
在地震学中,常常需要比较两列波的相似程度(重复地震探测常用),或两列波拟合程度(反演常用)。 要定量刻画这一需求,就需要计算两列波的互相关系数(Cross-Correlation, 简写为:CC)。 计算互相关系数的软件,代码…
r = xcorr(x,y) returns the cross-correlation of two discrete-time sequences. Cross-correlation measures the similarity between a vector x and shifted (lagged) copies of a vector y as a function of the lag. If x and y have different lengths, the function appends zeros to the end of th...

Compute the cross-correlation on the GPU. cc = xcorr2(offsetTemplate,template); Return the result to the MATLAB® workspace usinggather. Use the maximum absolute value of the cross-correlation to determine the shift, and compare the result with the known shift. ...
The cross correlation function xcorr in matlab provides the lag between two signals. But, Is there any matlab function that calculates the cross correlation between 2 signals and outputs a sigle value i.e < =1?댓글 수: 0 댓글을 달려면 로그인하십시오....
Find the peak in cross-correlation. Get [ypeak,xpeak] = find(c==max(c(:))); Account for the padding that normxcorr2 adds. Get yoffSet = ypeak-size(onion,1); xoffSet = xpeak-size(onion,2); Display the matched area by using the drawrectangle function. The 'Position' name-...

Align Signals Using Cross-CorrelationCopy Code Copy CommandMany measurements involve data collected asynchronously by multiple sensors. If you want to integrate the signals and study them in tandem, you have to synchronize them. Use xcorr for that purpose....
Normalized cross correlation 归一化互相关系数 Python 最近因为工作的关系需要使用matlab作为数据统计的工具,其中一个关键是使用其自相关函数获得数据的估计。自己只在本科时候马马虎虎地学习了一点matlab,这次仗着有C/C++的基础迅速地过了一遍自己需要的matlab的语法,原来这门语言很像脚本啊,同Python一样都是弱类型的,...
