FFT shift

[j_bossu]

Hi

Does it exist a function performing a shift of the FFT to have the origin in the center of the image.
Thanks

Hi

Invert sign for every odd pixel. Something like this:

for(int i=0; i {
Ipp32f *Row = (Ipp32f *)((char *)pSrc + i*srcStep);
for(int k=0; k {

if((i+k)&1)
Row = -Row;
}
}
