WebFast transforms compute them. To show the practical significance of wavelets, the book also provides transitions into several applications: analysis (detection of crashes, edges, or other events), compression (reduction of storage), smoothing (attenuation of noise), and syn thesis (reconstruction after compression or other modification). WebThis is the same as with the fast Fourier transform, where the transformed data also takes the same place as the input data. This in-place property makes the lifting wavelet transform very attractive for use in embedded applications, where memory and board space are still expensive. We conclude this section with a note on terminology.
