Abstract: | We generalize the notion of B-spline to the thin plate splines and to otherd-dimensional polyharmonic splines as defined in Duchon, 3]]; for regular nets, we give the main properties of these B-splines: Fourier transform, decay when x , stability, integration property, links between B-splines of different orders or of different dimensions and in particular link with the polynomial B-splines, approximation using B-splines... We show that, in some sense, B-splines may be considered as a regularized form of the Dirac distribution. |
