after not getting any response on my previous post, I'll try again. 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.
can you help me? can you supply a working 2D wavelet code that works with other border extension?
