Reconstructs a real valued signal from the output of crc
(wavelet case) by minimizing an appropriate quadratic form.
crcrec(siginput, inputwt, beemap, noct, nvoice, compr, minnbnodes=2,
w0=2 * pi, bstep=5, ptile=0.01, epsilon=0, fast=FALSE, para=5, real=FALSE,
plot=2)
original signal.
wavelet transform.
occupation measure, output of crc
.
number of octaves.
number of voices per octave.
compression rate for sampling the ridges.
minimal number of points per ridge.
center frequency of the wavelet.
size (in the time direction) of the steps for chaining.
relative threshold of occupation measure.
constant in front of the smoothness term in penalty function.
if set to TRUE, uses trapezoidal rule to evaluate $Q_2$.
scale parameter for extrapolating the ridges.
if set to TRUE, uses only real constraints.
1: displays signal,components,and reconstruction one after another. 2: displays signal, components and reconstruction.
Returns a structure containing the following elements:
reconstructed signal.
image of the ridges (with different colors).
2D array containing the signals reconstructed from ridges.
When ptile is high, boundary effects may appeare. para controls extrapolation of the ridge.
