skeleton2: Reconstruction from Dual Wavelet
Description
Computes the reconstructed signal from the ridge in the
case of real constraints.Usage
skeleton2(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.
