ABSTRACT
Haar transform unitary transform mapping N samples g(n) to N coefficients G(k) in a way that corresponds to repeated two-point averaging and two-point differencing. The 2 × 2 Haar transform is H 2 = 1 2 ( 1 1 1 − 1 ) . https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315214740/56242e4e-db3a-4952-92a8-e407fd08484a/content/unequ8_1.tif"/>
