First, I used mkl to compute forward the 2d fft of the initial image and I computed backward. I think it should get a image where every pixel gray scale is scaled by the factor (imagewidth*imageheight). However, only the right half of the image is scaled, and the other half is just the original image. How did that happen!</P> Mon, 17 Mar 2014 03:11:25 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Problem-with-scale-factor-in-2d-fft/m-p/948534#M15080 flexwang 2014-03-17T03:11:25Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Problem-with-scale-factor-in-2d-fft/m-p/948535#M15081 <P>Can you attach a testcase that reproduced this?</P> <P>--Vipin</P> <P>&nbsp;</P> Mon, 17 Mar 2014 04:44:19 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Problem-with-scale-factor-in-2d-fft/m-p/948535#M15081 VipinKumar_E_Intel 2014-03-17T04:44:19Z
