The lifting scheme is a technique used in the field of signal processing and wavelet analysis for constructing discrete wavelet transforms (DWT). It is particularly valued for its simplicity and efficiency in both implementation and computation. Introduced by Wim Sweldens in the 1990s, the lifting scheme provides a way to build wavelet transforms through a sequence of simple linear transformations rather than through convolutions.
