Removing noise from music using local trigonometric bases and wavelet packets

摘要: The work is closely based on the of R. Coifman and M.V. Wickerhauser entropy-based denoising algorithms RK F. Majid. An algorithm used in that work, which also here, consists broad outline choosing an optimal basis for a given signal from library local trigonometric wavelet packet bases. Optimality defined terms cost function. then spilt into clean noisy parts, procedure iterated component. components each iteration are added together
