I use dft with 8 real values.
I obtain result in 8 real Mat.
Correctly I interprete?
rows:
0 -0th harmonic, only real. im = 0 for this
1 - 1st harmonic real
2 - 1st harmonic imag
3 - 2nd harmonic real
4 - 2nd harmonic imag
5 - 3rd harmonic real
6 - 3rd harmonic imag
7 - 4th harmonic only real, imag for 4th is 0
?
How to use twodimensional DFT and hot to interpret results?
Maybe betteris using Mat with CV_64FC2 instead of CV_64F?
