An efficient spline basis for multi-dimensional applications: image interpolation

In this paper, we present a new spline basis function, the 2-5-2 spline which can be computed using simple fixed point shifts and adds. We compare the results of 2-5-2 spline image interpolation with the results using the most commonly used spline basis, the B-spline. We also present efficient computational algorithms for the new spline basis function.
