Abstract
The Letter deals with a new interpolation algorithm for 2-D data, base d on the least-squares optimisation of a spline-like scheme. First, an optimum least-squares bilinear interpolation is applied to uniform sa mpling. The problem of spatial adaptivity is then solved by recursive splitting. Finally, the technique is integrated into a two-source codi ng scheme.
