Maximal approximation order for a box-spline semi-cardinal interpolation scheme on the three-direction mesh
The authors study a new-cardinal interpolation scheme which is of the maximal approximation order 4. This scheme is developed for interpolation of a semi-plane lattice using the vertices from a subspace of box-spline space which is generated by centered 3-direction box-spline the direction matrix of which has every multiplicity 2.
