Complex images initialitzation

tesc — Fri, 08 Jun 2007 10:50:50 GMT

Hello All,

I'm using FFT to filter images in frequency domain by eliminating some frequency peaks. Aprox our proces is:

Convert Image 8u -> 32fc
MakeFFT
Get Mag/Pha from complex FFT image
Aply filtering inMag
Restore complex image from Mag/Pha
ApplyiFFT.
Get filtered image as magnitude of 32fc iFFT result

Is there any function to convert a 8u image to a 32fc image?.We can not find any way to do this and we are doing pixel by pixel with and standard 'for' bucle.

Thanks for your help.

Francesc

Hello,

you can use ippiConvert_8u32f and then ippsRealToCplx onrow by row basis.

Vladimir

Hello Vladimir,

Thanks for your response and sorry for my late reply. We have been very busy with other project and I have notworkied with IPP for all this time.

I will try, but it seems a good solution, nevertheless a fastest solution.

Regards,

Francesc
