skeleton: Reconstruction from Dual Wavelets
Description
Computes the reconstructed signal from the ridge, given
the inverse of the matrix Q.Usage
skeleton(cwtinput, Qinv, morvelets, bridge, aridge, N)
Arguments
cwtinput
continuous wavelet transform (as the output of cwt)
Qinv
inverse of the reconstruction kernel (2D array)
morvelets
array of Morlet wavelets located at the ridge samples
bridge
time coordinates of the ridge samples
aridge
scale coordinates of the ridge samples
N
size of reconstructed signal
Value
- Returns a list of the elements of the reconstruction of a signal from
sample points of a ridge
- solreconstruction from a ridge
- Amatrix of the inner products
- lamcoefficients of dual wavelets in reconstructed signal.
They are the Lagrange multipliers $\lambda$'s of the
text.
- dualwavearray containing the dual wavelets.
