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.</DIV> <DIV>I join my programm and my image.</DIV> <DIV>Thanks.</DIV> Thu, 22 Dec 2005 00:53:48 GMT https://community.intel.com/t5/Intel-Integrated-Performance/FFT-with-IPP/m-p/955953#M19083 j_bossu 2005-12-22T00:53:48Z https://community.intel.com/t5/Intel-Integrated-Performance/FFT-with-IPP/m-p/955954#M19084 <P>Hi,</P> <P>you have to allocate 1024x1024 buffer image and copy your image into it.</P> <P>Or you can use DFT on your original image.</P> <P>Regards,<BR /> Vladimir</P> <DIV></DIV> Fri, 23 Dec 2005 03:28:00 GMT https://community.intel.com/t5/Intel-Integrated-Performance/FFT-with-IPP/m-p/955954#M19084 Vladimir_Dudnik 2005-12-23T03:28:00Z https://community.intel.com/t5/Intel-Integrated-Performance/FFT-with-IPP/m-p/955955#M19085 <P>OK, it is ready.</P> <P></P> <P>Thanks a lot.</P> <DIV></DIV> Sat, 07 Jan 2006 01:26:27 GMT https://community.intel.com/t5/Intel-Integrated-Performance/FFT-with-IPP/m-p/955955#M19085 j_bossu 2006-01-07T01:26:27Z
