Why ippiDistance is so slow?
For theChebyshev metric,my straightfoward C++ implementation easily outperforms ippiDistance and gives the same result.... The only difference is that output of my "Distance Transform" is "Ipp8u" with saturation to 255 (this saturation limit israrely reached in practice). But ippiDistance's output is "Ipp32f", which, IMO, is an overkill for most popular metrics.
