An extrapolation procedure based on the vanishing moments property of the orthonormal wavelet family is associated to the a trous discrete wavelet transform with filters taken from the biorthogonal spline wavelets. This coupling avoids the construction of wavelets in the interval, enabling the confidence region increase of the transform when analyzing data. Simulations corroborate the efficiency of the proposed scheme.
