The Letter deals 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.

Abstract
The Letter deals 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. © 1993, The Institution of Electrical Engineers. All rights reserved.File in questo prodotto:
