I'm trying to use Hamming window functions in my program before applying FFT on images. There are two image processing functions for Hamming: ippiWinHamming_32f_C1IR and ippiWinHammingSep_32f_C1IR. I do not know which one should I use.
Can someone tell me whats the difference between those two hamming ippi functions? What effect will be there if I choose ippiWinHamming_32f_C1IR over ippiWinHammingSep_32f_C1IR on FFT?
