许多测量涉及多个传感器异步采集的数据。如果您要集成信号并以关联式研究它们,您必须同步它们。为此,请使用xcorr。 例如,假设有一辆汽车经过一座桥。它产生的振动由位于不同位置的三个相同传感器进行测量。信号有不同到达时间。 将信号加载到 MATLAB® 工作区并进行绘图。

can someone tell how to do the cross-correlation of two speech signals (each of 40,000 samples) in MATLAB without using the built-in function xcorr and the correlation coefficient? Thanks in advance. matlab signal-processing cross-correlation Share Improve this question Follow edited Oct 1...
I am struggling with template matching in the Fourier domain in Matlab. Here are my images (the artist is RamalamaCreatures on DeviantArt): My aim is to place a bounding box around the ear of the possum, like this example (where I performed template matching using normxcorr2): Here is...
