recmultmodulationTI |
|
Translation Invariant Multiple Modulation Estimator |
DESCRIPTION
Estimate the intensity function using the translation invariant version of a multiple modulation estimator based on a partition of length [loge(logen)].
USAGE
f = recmultmodulationTI(signal,lev,h)
REQUIRED ARGUMENTS | ||
signal |
1-d Noisy signal, length(signal)= 2^J | |
lev |
Coarsest resolution level | |
h |
Quadrature mirror filter for wavelet transform | |
OPTIONAL ARGUMENTS | ||
h |
Optional, Default = Symmlet 8 | |
lev |
Optional, Default= 4 | |
VALUE | ||
f |
Estimated intensity function |
BACKGROUND
The procedure has been developed by Antoniadis and Sapatinas (2001) and is based on modulation estimators.
