Hanning) comes at a lesser computational cost than that for a polynomial-based one, is about W = 6 in two dimensions. For images or volumes, where q> 1, it is important to realize that this result does not imply that the use of sinc functions is more efficient than that of polynomials, because sinc typically requires a larger support than polynomials to reach the same quality. Since the global cost is 0(Wq), and since q>1, any increase in W dominates over the other terms.
