DWT denotes discrete wavelet transforms, instances of continuous wavelet transforms that admit a discrete sampling.
Discrete wavelet transforms (DWT) are instances of continuous wavelet transforms that admit a discrete sampling. They are interpreted as bases and frames used in numerical and functional analysis and data proceeding. The Haar and the Franklin wavelets are among the first known DWTs. The DWT often denotes orthogonal and biorthogonal bases and redundant frames, partially decimated wavelets, wavelet packets. Discretization of the wavelet parameters may arise in time, space, frequency, direction.
