Fast lagrange interpolation

Local interpolations are required during aggregation and disaggregation stages of MLFMA in order to match the different sampling rates for the radiated and incoming fields in consecutive levels. The conventional one-step Lagrange interpolation In He’s frequency formulation, the location points play an important role, generally we choose 1 2 A , but other location points can be also chosen, for examples, 3 10 A , 1 2 A and 7 10 A , in order to make the method more mathematically rigorous, the Gaussian interpolation 20 can be adopted Barycentric interpolation is a variant of Lagrange polynomial interpolation that is fast and stable. It deserves to be known as the standard method of polynomial interpolation. Lagrange Interpolation Lagrange interpolation is a well known, classical technique for interpolation . It is also called Waring-Lagrange interpolation, since Waring actually published it 16 years before Lagrange [309, p. 323].

The contributions of this paper include: { We propose a general fast guided interpolation (FGI) approach for both 1) noisy but regularly distributed depth maps and 2) typically reliable but highly scattered motion data.
