On time-dependent wavelet denoising
Brani Vidaković, C.B. Lozoya · IEEE Transactions on Signal Processing · 1998
The authors address the shrinkage of wavelet coefficients and induced denoising in the time domain by taking into consideration the "time" behavior of a noisy signal. They illustrate the time adaptation paradigm in a thresholding procedure utilizing Bayesian hypothesis tests. Both one-dimensional (1-D) and two-dimensional (2-D) signals are considered in examples to motivate and implement the method.
