A fast mellin and scale transform

WebThe question is quite broad, but here is a possible relation between Fourier transformation and prime numbers. We know that the Riemann zeta function is defined as $$\zeta (s) = \sum_ {n=1}^\infty\frac {1} {n^s},$$ for all $\Re (s)>1$. The second thing, that the Riemann zeta function is related to prime numbers via Euler product formula. for ... WebMellin and scale transforms are important in vision and image processing. In particular, a so-called Fourier-Mellin transform can be used for pattern recognition for its in-variance to …
