regrec2 | R Documentation |

Reconstructs signal from a “regularly sampled” ridge, in the wavelet case, from a precomputed kernel.

regrec2(siginput, cwtinput, phi, nbnodes, noct, nvoice, Q2, epsilon=0.5, w0=2 * pi, plot=FALSE)

`siginput` |
input signal. |

`cwtinput` |
wavelet transform, output of |

`phi` |
unsampled ridge. |

`nbnodes` |
number of samples on the ridge |

`noct` |
number of octaves (powers of 2) |

`nvoice` |
number of different scales per octave |

`Q2` |
second term of the reconstruction kernel |

`epsilon` |
coefficient of the |

`w0` |
central frequency of Morlet wavelet |

`plot` |
if set to TRUE, displays original and reconstructed signals |

The computation of the kernel may be time consuming. This function avoids recomputing it if it was computed already.

Returns a list containing:

`sol` |
reconstruction from a ridge. |

`A` |
<wavelets,dualwavelets> matrix. |

`lam` |
coefficients of dual wavelets in reconstructed signal. |

`dualwave` |
array containing the dual wavelets. |

`morvelets` |
array containing the wavelets on sampled ridge. |

`solskel` |
wavelet transform of sol, restricted to the ridge. |

`inputskel` |
wavelet transform of signal, restricted to the ridge. |

`nbnodes` |
number of nodes used for the reconstruction. |
