About

Hough Spectrum(HS) is basically a translation invariant function on the corresponding Hough Transform(HT). This means that this spectrum only affects on the rotation. Any translation done does not change the result.

Use

Hough Spectrum in our case used to find the best rotation on one map to overlap another. Two Hough Spectrums with cross correlation outputs the estimates rotation.
