    The other types correspond to oversampled wavelet transforms.
    The oversampled DWT (discrete wavelet transform) presented in this double density DWT is redundant by a factor of two regardless of the number of scales.

    This chapter takes up the design of discrete wavelet transforms based on oversampled filter banks. In this case the wavelets form an overcomplete basis.
