WebCross-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 the shorter vector so it has the same length as the other. example. r = xcorr (x) returns the autocorrelation sequence of x. WebInput image, specified as a numeric image. A must be larger than the matrix template for the normalization to be meaningful.. Normalized cross-correlation is an undefined …
How to find a maximal possible value of a cross correlation
Web12 de abr. de 2024 · Briefly, a zero-mean normalized cross-correlation (ZNCC) function is used to perform a coarse search. The correlation calculation is guided by the ZNCC coefficient to find the displacements in integer pixel. Then, the obtained displacements are input as the initial values to the sub-pixel fine search of the IC-GN iterative method.
