Reconstructs signal from a ``regularly sampled'' ridge, in the Gabor case.
gregrec(siginput, gtinput, phi, nbnodes, nvoice, freqstep, scale,
epsilon=0, fast=FALSE, plot=FALSE, para=0, hflag=FALSE, real=FALSE,
check=FALSE)input signal.
Gabor transform, output of cgt.
unsampled ridge.
number of nodes used for the reconstruction.
number of different scales per octave
sampling rate for the frequency axis
size parameter for the Gabor function.
coefficient of the \(Q_2\) term in reconstruction kernel
if set to T, the kernel is computed using trapezoidal rule.
if set to TRUE, displays original and reconstructed signals
scale parameter for extrapolating the ridges.
if set to TRUE, uses \(Q_1\) as first term in the kernel.
if set to TRUE, uses only real constraints on the transform.
if set to TRUE, computes cwt of
reconstructed signal.
Returns a list containing:
reconstruction from a ridge.
<gaborlets,dualgaborlets> matrix.
coefficients of dual wavelets in reconstructed signal.
array containing the dual wavelets.
array containing the wavelets on sampled ridge.
Gabor transform of sol, restricted to the ridge.
Gabor transform of signal, restricted to the ridge.
second part of the reconstruction kernel.
