Phase Shift for Hilbert Wavelet Coefficients
Description
Wavelet coefficients are circularly shifted by the amount of phase shift induced by the discrete Hilbert wavelet transform.
Usage
phase.shift.hilbert(x, wf)
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.
