What does Xcorr mean in Matlab?
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.
How do you improve cross-correlation?
The improvement is achieved by applying an upper limit to the grayscale values of the images. This image enhancement, called Intensity Capping, is performed before the image pair is analyzed using the cross-correlation.
How do you find the cross-correlation of two sequences?
To detect a level of correlation between two signals we use cross-correlation. It is calculated simply by multiplying and summing two-time series together. In the following example, graphs A and B are cross-correlated but graph C is not correlated to either.
