Crazy Climbers Reconstruction by Penalization
Reconstructs a real valued signal from the output of
(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)
occupation measure, output of
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.
When ptile is high, boundary effects may appeare. para controls extrapolation of the ridge.
Returns a structure containing the following elements:
image of the ridges (with different colors).
2D array containing the signals reconstructed from ridges.
