appcoef2
2-D approximation coefficients
Description
Examples
Input Arguments
Output Arguments
Algorithms
The input vector C
and bookkeeping matrix S
contain all the information about the 2-D signal decomposition.
Let NMAX = size(S,1)-2
; then C = [A(NMAX) H(NMAX) V(NMAX)
D(NMAX) … H(1) V(1) D(1)]
where A
,
H
, V
, and D
are vectors. If
N = NMAX
, then a simple extraction is done; otherwise,
appcoef2
computes iteratively the approximation coefficients
using the inverse wavelet transform.
