Example of rotational alignment of two patterns with different bandwidths. In magenta, the original pattern f (Dirac delta with N = 4); in black, the rotated and directionally reduced pattern g (with ζ = 40%); in red, pattern f after rotational alignment with the estimated matrix . We observe that the rotation matching is still effective, although the main lobes of the patterns are not perfectly aligned (). The correlation coefficient is .
