If you are using FRC to compare different images or conditions, and your images do not change size, then the relative differences are still perfectly valid, but absolute values might be off.

A remark from Brian Patton, University of Strathclyde, Glasgow says that the original computation for the numerator was wrong, namely:
numerator[i] = dataA1[i] * dataA2[i] + dataB1[i] * dataB2[i];
And should be instead:
abs((FFT(Image1)*Complex_Conj(FFT(Image2)))
