Is there a example with FFT on image using MKL?

Hi,

It's the first time using the MKL.

I wonder is there a example code to show how to use MKL to do 2D FFT on image?

Does MKL support pthread?

Thanks

Any hint will be appreciated!

Hello Xiaojia

You can take image as 2D array, then you can find some 2D FFT c sample codes in MKL install folder or web article.

MKL support several model like sequential, internal openmp threads and tbb threads, which are suppose be work with external pthread.

If you have any question, please submit your question to https://supporttickets.intel.com.

Best Regards,

Ying

Hi,

MKL support N-dimensional FFT computing, you could follow developer reference or MKL examples saved locally when you install the MKL, the path is $MKLROOT/examples.

MKL threading is using OpenMP/TBB, but you could write pthread program to control outside.

Best regards,
