• interCor(correlogram, F, G) -> It implements a new sequence compared to the mother method "interCor". First, the norm of F and G are stored within correlogram buffer. Then F and G are normalized and then provided to the mother method Ccorrelation_blockMatch<T>::interCor. Thus correlation is performed only on the phase part of the f and g signal.
• normalized(correlogram, F, G) -> phases are calculated from F = F/||F|| and G = G/||G||. Notice a filtering is performed for low value of ||...|| compared to maximal one. It avoids notably any zero division. !!!!!!!!! Currently the thresholding m_factor is totally arbitrary.
