In all of the frames studied so far, the analysis (computation of ƒ (Ψ, t) or ƒ ( s , t) or their discrete samples) must be made directly by computing the relevant integrals for all the necessary values of the time-frequency or timescale parameters. Around 1986, a radically new method for performing discrete wavelet analysis and synthesis was born, known as multiresolution analysis. This method is completely recursive and therefore ideal for computations.
