  We show that Mellin moments of generalized parton distributions, given as
even polynomials in the skewness parameter, are obtained from the Taylor
expansion of light front wave functions. Furthermore, we derive non-standard
versions of the inverse Radon transform to obtain the double distribution from
the parton number conserved light front wave function overlap. These
transformations are utilized to extend a generalized parton distribution from
the outer region to the central one. We exemplify the formalism for a light
front wave function that arises from an AdS/QCD duality conjecture.
