FFT with IPP

[j_bossu]

Hello,

Well, I must proceed a FFT on a Image follows on IFFT to find the original image.

The size of image is : width=562 and height=604.

I make the FFT on 1024*1024 but the programm crashes. However, if I make the FFT with 512*512, I have the good result, I obtain the original image but the size is 512*512 so to have an image with 562*604, I must this FFT on 1024*1024.

I join my programm and my image.

Thanks.

Hi,

you have to allocate 1024x1024 buffer image and copy your image into it.

Or you can use DFT on your original image.

OK, it is ready.

Thanks a lot.
