摘要
A system and method for rating the validity of multiple data processing algorithms A1-An on a set of multi-dimensional input data I where P1-Pn is the output data produced by the competing algorithms. Processing steps include: (1) computing the Fourier Transform or the phase congruence of the input data I, (2) computing the Fourier Transform or the phase congruence of the output data P1-Pn, (3) computing the phase of the data computed at step 1, (4) computing the phases of the data computed at step 2, and (5) computing a similarity metric, such as the normalized cross correlation of each phase computed at step 4 with the corresponding phase computed at step 3. The similarity metrics computed at step 5 can be ordered to provide a ranking of the algorithm validity.
