The Fractional Hilbert Transform And Dual-Tree Gabor-Like Wavelet Analysis
2009
2009 Ieee International Conference On Acoustics, Speech, And Signal Processing, Vols 1- 8, Proceedings
We provide an amplitude-phase representation of the dual-tree complex wavelet transform by extending the fixed quadrature relationship of the dual-tree wavelets to arbitrary phase-shifts using the fractional Hilbert transform. (fHT). The fHT is a generalization of the Hilbert transform that extends the quadrature phase-shift action of the latter to arbitrary phase-shifts-a real shift parameter controls this phase-shift action.
