A novel improvement to an existing wavelet representation is presented within the context of analysis and synthesis of harmonic audio signals. The approach replaces the discrete wavelet transform stage in the harmonic-band wavelet transform with the dual-tree complex wavelet transform. The harmonic-…
This paper describes the application of belief propagation methods to image fusion within a complex wavelet decomposition (the Dual Tree Complex Wavelet Transform: DT-CWT). Belief propagation within each transform subband iterates through a lattice based Bayesian belief network. This leads to precis…
A novel adaptation of the two dimensional Homomorphic filter is introduced using the Dual Tree Complex Wavelet Transform for improved illumination invariant processing. The Homomorphic filter is conventionally implemented within the log-Fourier domain using an isotropic high-pass filter based on the…
