Description

Wavelet coefficients are circularly shifted by the amount of phase shift induced by the discrete Hilbert wavelet transform.

Usage

1
2

Arguments

x

Discete Hilbert wavelet transform (DHWT) object.

wf

character string; Hilbert wavelet pair used in DHWT

Details

The "center-of-energy" argument of Hess-Nielsen and Wickerhauser (1996) is used to provide a flexible way to circularly shift wavelet coefficients regardless of the wavelet filter used.

Value

DHWT (DHWPT) object with coefficients circularly shifted.
