... Wavelet analysis works most convincingly on complicated data sets. ... These wavelet maps promptly represent an overwhelming amount of information, that must be reduced in order to be useful. The reduction can take two basic different forms, and countless variants. In the sift-and-discard approach, features of interest are enhanced and the rest is removed from the wavelet maps: applications such as denoising or event identification are representative. ...
