Abstract
The usefulness of unidimensional functions calculated from the power spectrum to determine the relative orientation between two analogous images is discussed. The results of the calculation obtained by the correlation of these unidimensional functions are compared with those obtained by two-dimensional angular correlation in order to test the precision of the method. One of the functions with a simple experimental realization yields results that are comparable to the others, including the two-dimensional function, which results in a considerable simplification in the digital determination of the rotation angle.
