https://community.intel.com/t5/Intel-Integrated-Performance/bug-in-IPP-2D-wavelet-transform/m-p/809244#M3809 Hello again,<BR /><BR />after not getting any response on my previous post, I'll try again.<BR />I think there is a bug with ipp 2D wavelet transform (ippiWTFwd, ippiWTInv). they don't seem to work with any border extension except ippiCopyWrapBorder. ippiCopyReplicateBorder_32f_C1R or symmetric extension that I wrote myself does not work (I can't reconstruct the image). since ippiCopyReplicateBorder_32f_C1R and ippiCopyWrapBorder_32f_C1R have exactly the same interface, I can't see how one works and the other does not on the same data.<BR /><BR />can you help me? can you supply a working 2D wavelet code that works with other border extension?<BR /><BR />thanks,<BR /><BR />Yoav<BR /> Sun, 10 Oct 2010 09:11:35 GMT yoavnaveh 2010-10-10T09:11:35Z https://community.intel.com/t5/Intel-Integrated-Performance/bug-in-IPP-2D-wavelet-transform/m-p/809244#M3809 Hello again,<BR /><BR />after not getting any response on my previous post, I'll try again.<BR />I think there is a bug with ipp 2D wavelet transform (ippiWTFwd, ippiWTInv). they don't seem to work with any border extension except ippiCopyWrapBorder. ippiCopyReplicateBorder_32f_C1R or symmetric extension that I wrote myself does not work (I can't reconstruct the image). since ippiCopyReplicateBorder_32f_C1R and ippiCopyWrapBorder_32f_C1R have exactly the same interface, I can't see how one works and the other does not on the same data.<BR /><BR />can you help me? can you supply a working 2D wavelet code that works with other border extension?<BR /><BR />thanks,<BR /><BR />Yoav<BR /> Sun, 10 Oct 2010 09:11:35 GMT https://community.intel.com/t5/Intel-Integrated-Performance/bug-in-IPP-2D-wavelet-transform/m-p/809244#M3809 yoavnaveh 2010-10-10T09:11:35Z https://community.intel.com/t5/Intel-Integrated-Performance/bug-in-IPP-2D-wavelet-transform/m-p/809245#M3810 <P>Hi Yoav, </P><P>I added some note in your post before.
