Wavelet packets frames in multiresolution structures

Often, in signal processing applications, it is useful and convenient to have on the hand flexible tools providing time-frequency information from the wavelet coefficients. This means the well known wavelet packets techniques. The main purpose of this work is to explore and discuss several alternatives in this field, related to orthogonal spline wavelets.
