This modules computes the inverse B-spline transform of a two-dimensionnal array of numbers (Fimage). A mirror extension is used at the boundaries of the array. The coefficients out(k, l ) are computed in order to ensure that the B-spline interpolation
fcropmodule. The order of the spline n (order) must be between 2 and 11. The module is based on a recursive implementation of the associated z-filter (see [TBU99][UAE91]).
