Hello,

I'm a bit puzzled with the general DCT transform in IPP v3.0 (not the 8x8 versions).

After forward transforming an image, the inverse transform of this transformed image doesn't yield the original image. Is this normal? I've called both initialisation functions (forward and inverse) and I'm working with the 32f_C1R version of the functions.

By the way, are the low frequencies of the transform at the begining of the image (nearest to the original image pointer)?

Hope someone can help!
