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,
Description r= xcorr(x,y)returns thecross-correlationof two discrete-time sequences. Cross-correlation measures the similarity between a vectorxand shifted (lagged) copies of a vectoryas a function of the lag. Ifxandyhave different lengths, the function appends zeros to the end of the shorter...
0 링크 번역 편집:Adam Danz2023년 1월 10일 채택된 답변:Adam Danz 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...
I was trying to emphasize that I'm wondering if the community knows of a function in Matlab that is more suitable to what I'm looking for, since xcorr doesn't seem to be producing a "universal" normalized vector (i.e., sometimes a vector produced from the correlation will hav...
A positive column index corresponds to a rightward shift of the columns ofH. To cast the indices in MATLAB®form, add the size ofH: the elementC(k,l) corresponds toC(k+P,l+Q)in the workspace. For example, consider this 2-D cross-correlation: ...
This MATLAB function computes the time delay, tau, between the signal, sig, and a reference signal, refsig.
Display the matched area by using the drawrectangle function. The 'Position' name-value pair argument specifies the upper left coordinate, width, and height of the ROI as the 4-element vector [xmin,ymin,width,height]. Specify the face of the ROI as fully transparent. Get imshow(peppers)...
Cross-correlation functionWavelet transformIn this paper, a novel hybrid method based on discrete wavelet transform (DWT) and cross-correlation function (CCF) is proposed for the differential protection of the power transformers. The key idea of using the wavelet transform is the existence of high-...
This paper describes a MATLAB program with a graphical user interface (GUI), for a signal processing based on the Auditory Image Model [S. Bleeck et al., Acta Acustica united with Acustica, 90 (2004) 781-787], followed by the summary autocorrelation function (SACF) and the summary ...
