how to use ippiCrossCorrFull_NormLevel_32f_C3R

[feridanes]

Hi,

I'm trying to use "ippiCrossCorrFull_NormLevel_32f_C3R" and i get IND and QNAN value as a result and i am trying to debug my function.

My question is the template argument of this API has tobe 3 channel as well thanks???

Any other inputs are welcome....

regards

Feri
