Resampling hierarchical processes in the wavelet domain: A case study using atmospheric turbulence
(Georgia Institute of Technology, 2004-05-20)
There is a growing need for statistical methods that generate an ensemble of plausible realizations of a hierarchical process from a single run or experiment. The main challenge is how to construct such an ensemble in a ...
Γ -Minimax Wavelet Shrinkage: A Robust Incorporation of Information about Energy of a Signal in Denoising Applications
(Georgia Institute of Technology, 2001)
In this paper we propose a method for wavelet- filtering of noisy signals when prior information about the energy of the signal of interest is available. Assuming the independence model, according to which the wavelet ...
