  • Abstract
    The authors deal with a new interpolation algorithm for 2-D data, based on the least-squares optimisation of a spline-like scheme. First, an optimum least-squares bilinear interpolation is applied to uniform sampling. The problem of spatial adaptivity is then solved by recursive splitting. Finally, the technique is integrated into a two-source coding scheme.
